What Is a Foot to Centimeter Converter?

A foot to centimeter converter is a length conversion tool that turns imperial foot measurements into the metric centimeter unit, while also covering the inches that go with feet and the meters that go with centimeters. One foot is defined as exactly 30.48 cm, so the math is stable and the converter runs in both directions without losing precision.

  • Height in centimeters: Convert a height such as 5 ft 8 in to 172.72 cm for medical forms, IDs, or fitness apps.
  • Furniture and home projects: Translate product dimensions in feet into centimeters when ordering from a metric-country retailer or fitting a metric pattern.
  • Travel and maps: Switch trail signs, trailhead boards, or guidebook distances from feet to centimeters and meters for trip planning.
  • Reverse lookup: Enter a centimeter value (for example 100 cm) and read the feet and inches equivalent for patterns, fabric, or survey notes.

Most everyday length conversions sit between 1 foot (30.48 cm) and 10 feet (304.8 cm), so a converter that keeps four decimals covers the bulk of real-world use cases. The tool also surfaces meters when a meter reading is more comfortable than a long centimeter number.

Use this foot to centimeter converter whenever you have a number in feet and need it in centimeters, or you have a number in centimeters and need the closest feet and inches. The foot to centimeter converter also keeps the inch and meter outputs in sync so you can switch between metric and imperial without a second calculator.

If you only need the inch half of the conversion, In to cm Calculator handles the smaller imperial unit with the same 2.54 factor.

How the Foot to Centimeter Conversion Works

The conversion relies on two internationally fixed values: 1 foot is exactly 0.3048 meters (30.48 centimeters) and 1 inch is exactly 2.54 centimeters. Both definitions are baked into every length conversion result on this page.

centimeters = (feet × 12 + inches) × 2.54
  • feet: The whole-foot portion of the imperial length, entered as a number (integer or decimal) at least 0.
  • inches: The remaining inch portion of the imperial length, between 0 and just under 12, supporting decimals and fractions such as 1/2, 1/4, 5/8.
  • centimeters: The metric value used in the reverse workflow, entered in the centimeters field to compute feet and inches.

The meters output is the centimeter result divided by 100, so a single step scales centimeters into meters for any metric workflow that prefers meters. The reverse path uses the same 2.54 cm/in factor to walk centimeters back into inches, then splits those inches into a whole-foot portion and the leftover inches.

The result panel reflects whichever input you changed most recently. Editing the Feet or Inches field produces a cm and m result derived from those imperial values; editing the Centimeters field produces a cm and m result that matches what you typed and fills the Feet and Inches input fields with the matching feet and inches. All four outputs stay in one consistent pass.

5 feet 8 inches (a common adult height)

feet = 5, inches = 8

centimeters = (5 × 12 + 8) × 2.54 = (60 + 8) × 2.54 = 172.72 cm

172.72 cm (1.7272 m)

This is the height in centimeters that a 5 ft 8 in person would report on a metric form. The meters value of 1.7272 m is also surfaced in the result panel.

Reverse: 100 centimeters to feet and inches

centimeters = 100

total inches = 100 / 2.54 = 39.3701 in, then 39.3701 in = 3 ft 3.3701 in

3 ft 3.37 in

Use this reverse step when you know a length in centimeters (such as a fabric width) and need to read it in feet and inches for a US-based workshop.

According to NIST, the international foot is 0.3048 m (30.48 cm) and the inch is 2.54 cm. The same definitions appear in the BIPM SI Brochure, which traces the foot back to the international yard and pound agreement of 1 July 1959.

When the meters value is the only output you need, ft to m Calculator skips the centimeter step.

Key Concepts Explained

Four short definitions make the converter easier to read, especially when dealing with heights or fractional inches.

Imperial foot

A US customary and historical UK unit, defined since 1959 as exactly 0.3048 meters (30.48 centimeters). Used for personal height, real estate, and many construction plans in the United States.

Centimeter

A metric unit equal to one hundredth of a meter and 10 millimeters. Standard for body measurements, school rulers, fabric widths, and most scientific and medical documentation outside the US.

Inch (1/12 foot)

The smaller imperial unit that pairs with feet, defined as exactly 2.54 centimeters. Inches are commonly written as decimals (5.5 in) or fractions (5 1/2, 5 3/8) on tape measures.

Conversion factor 30.48

The exact number of centimeters in one foot, derived from 12 inches per foot × 2.54 cm per inch. Using 30.48 avoids the rounding error of 30.5 or other approximations.

These four terms cover what the calculator does: it reads feet and inches and turns them into centimeters and meters, or it reads centimeters and splits them into feet and inches. Knowing 30.48 is exact, not approximate, is what makes the output trustworthy for medical, surveying, and engineering workflows.

To see how the centimeter output of this tool scales into meters in a dedicated view, cm to m Calculator handles the single-step metric conversion.

How to Use This Calculator

Enter a value in any of the three input fields and the result panel updates in real time. The calculator handles feet-only, feet + inches, and pure centimeter input.

  1. 1 Type the feet value: Enter the whole-foot portion in the Feet field, e.g. 5 for 5 ft. Decimals such as 5.5 are accepted for half-foot entries.
  2. 2 Add the leftover inches: For a feet + inches length (such as 5 ft 8 in), put the inches in the Inches field. Decimals like 8.5 and fractions like 8 1/2 both work.
  3. 3 Read the centimeter result: Watch the Centimeters (cm) value update as you type. The default precision is four decimals, which is exact for most practical lengths.
  4. 4 Check the meters value: Read the Meters (m) line for a metric-friendly value, most useful for room dimensions, trail distances, and scientific reports.
  5. 5 Reverse convert from centimeters: Edit the Centimeters field for the reverse workflow. The result panel re-bins the value into feet and inches.
  6. 6 Use Reset to start over: Press Reset to return to the 1 ft / 30.48 cm default and clear in-progress edits.

To log a height of 5 ft 8 in on a metric form, type 5 in Feet, 8 in Inches, and read 172.72 cm. To convert a 100 cm baby length into feet and inches for a US pediatrician, type 100 in Centimeters and read 3 ft 3.37 in.

If you have a length in meters and want the matching feet and inches, Meters to Feet Calculator covers the same reverse workflow starting from a larger metric unit.

Benefits of Using This Calculator

The converter saves time and removes the two most common error sources in length math: rounding 30.5 instead of 30.48, and forgetting the inches paired with feet.

  • Exact 30.48 factor: Uses the internationally fixed 30.48 cm per foot, so even 100-foot measurements stay accurate to the millimeter.
  • Feet + inches support: Handles the way heights, sewing patterns, and lumber dimensions are usually written (5 ft 8 in, 6 ft 2 in) without pre-converting to decimal feet.
  • Bi-directional: Switch from imperial to metric or back in the same panel, so a metric pattern and a US tape measure can be cross-checked in one place.
  • Centimeters and meters together: Surfaces both cm and m for the same length, so you can read the precise number for a medical form and the rounded meter value for a project plan.
  • Mobile-friendly: Real-time updates and a results panel that scrolls into view on mobile mean you can run a conversion on a phone in a store, clinic, or fabric shop.

For users who move between US customary and metric length units, the calculator is faster than typing the math into a spreadsheet and more reliable than memory-based conversions. It also serves as a check against rounded factors in older textbooks.

For other height-related conversions such as inches to feet only or centimeters to a stand-alone height reading, Height Converter is a useful companion when height is the only data you have.

Factors That Affect Your Results

The output is governed by exact definitions, but a few choices about how the input is written and how the result is displayed still affect the final reading.

Input precision

Feet can be entered as integers, decimals, or fractions; the more digits you provide, the more precise the centimeter result. Rounding 5.58 ft to 6 ft shifts the centimeter output by about 12.7 cm.

Rounding rule

Centimeters are rounded to 4 decimals (0.0001 cm = 1 μm) and reverse inches to 2 decimals, which is more than enough for everyday lengths.

International vs US survey foot

The international foot of 0.3048 m is the standard for almost every modern use, including heights, product specs, and everyday construction. The older US survey foot (1200/3937 m) is a third decimal off and only matters in legacy US surveying data.

Inches convention

Inches are reported as 0 to 11.99 in the imperial direction. If you enter 12 in or higher, the overflow rolls into Feet; if you enter only centimeters, the leftover inches are reported between 0 and 11.99.

  • Fractional inches such as 1/2 or 5/8 are converted to decimals, but the reverse result reports inches to 2 decimals. If you need a 1/16-inch reading, treat the result as a starting point and measure the original length on a tape.
  • The calculator uses the international foot of 0.3048 m. For US survey feet (used in some older state-plane coordinates), divide the result by 0.3048006096 to get the survey-foot value.

These caveats rarely matter for everyday lengths, but they are worth knowing if you are working with surveying, aerospace, or scientific data that needs the survey foot or a fractional inch reading.

According to NIST Weights and Measures, the international foot is the standard for everyday use while the survey foot is a legacy exception

When the length uses a unit other than feet or centimeters, such as miles, yards, or millimeters, Length Converter gives a broader length grid that complements this foot-to-centimeter page.

Frequently Asked Questions

Q: How many centimeters are in 1 foot?

A: There are exactly 30.48 centimeters in 1 foot. That number comes from 12 inches per foot times 2.54 centimeters per inch, the same values the international yard and pound agreement of 1959 set for both units.

Q: What is 5 feet 8 inches in cm?

A: 5 ft 8 in equals 172.72 cm. Add the inches to the feet (5 × 12 + 8 = 68 in), then multiply by 2.54 cm/in to get 172.72 cm, or 1.7272 m for metric specifications.

Q: How do you convert feet and inches to centimeters?

A: Convert feet to inches by multiplying by 12, add the remaining inches, then multiply the total inches by 2.54. The reverse direction divides centimeters by 2.54 to get inches, then splits those inches into a whole-foot portion and the leftover inches.

Q: What is 6 feet in cm?

A: 6 feet equals exactly 182.88 cm, or 1.8288 m. Multiply 6 by 30.48 (the exact centimeters-per-foot factor) to get 182.88 cm without rounding error.

Q: How accurate is the foot to centimeter conversion?

A: The conversion uses the exact international foot of 0.3048 m, so the centimeter and meter outputs are exact to the rounding rule of the calculator. The only loss of precision comes from how many digits you enter in the Feet, Inches, or Centimeters field.

Q: How do I convert centimeters back to feet?

A: Divide the centimeter value by 2.54 to get total inches, then divide that by 12 to get a whole-foot reading. The leftover inches (total inches minus feet × 12) is the inch portion. For example, 100 cm equals 39.37 in, which is 3 ft 3.37 in.
