CM to Feet Converter — Convert Centimeters to Feet Instantly

About Centimeters to Feet Conversion

Centimeters (cm) and feet (ft) both measure length, but they belong to different systems: centimeters to the metric (SI) system and feet to U.S. customary units. Converting cm → ft is common for body height, furniture and décor sizing, woodworking layouts, and collaboration on mixed-unit drawings. If your tape measures or plans are marked in feet and inches, converting from centimeters keeps your work consistent with field practice.

The relationship is exact: 1 foot = 30.48 centimeters. Because 1 inch is defined as exactly 2.54 cm and a foot is 12 inches, no approximations are involved. Divide centimeters by 30.48 to get feet; multiply feet by 30.48 to get centimeters. For feet-and-inches, convert to total inches first (cm ÷ 2.54), then split into feet and the remainder inches.

CM to Feet Formula

Exact relationship

Use the factor method:

feet = centimeters ÷ 30.48

Example:

170 cm = 170 ÷ 30.48 = 5.57743 ft

Reverse calculation (ft → cm)

Multiply by 30.48: centimeters = feet × 30.48.

What is a Centimeter?

A centimeter is a metric unit equal to one hundredth of a meter. It’s widely used for body measurements, product specs, and technical drawings. The metric system’s decimal structure (mm ⇄ cm ⇄ m) makes scaling simple and minimizes arithmetic error when switching magnitudes.

What is a Foot?

A foot is a U.S. customary unit of length equal to exactly 12 inches. It’s commonly paired with inches for expressing room sizes, woodworking cut lists, and architectural dimensions (for example, 8′ 6″). On drawings, the prime (′) denotes feet and the double-prime (″) denotes inches.

Step-by-Step: Converting cm to ft (and inches)

Write the measurement in centimeters.
Divide by 30.48 to get feet (decimals allowed).
For feet-and-inches format, convert cm to inches (inches = cm ÷ 2.54), take whole feet (floor(inches ÷ 12)), and use the remainder as inches.

Example walkthrough (feet + inches):

Input:  170 cm
Inches: 170 ÷ 2.54 = 66.9291 in
Feet:   floor(66.9291 ÷ 12) = 5
Remainder inches: 66.9291 − (5 × 12) = 6.9291 in
Output: 5 ft 6.93 in (approx)

Frequently Asked Questions

How do you convert centimeters to feet?

Use the exact formula: feet = centimeters ÷ 30.48. Since 1 foot equals exactly 30.48 centimeters, dividing by 30.48 converts any centimeter measurement to feet.

What is 1 centimeter in feet?

1 centimeter = 1 ÷ 30.48 ≈ 0.0328084 feet.

How many feet is 170 cm?

170 ÷ 30.48 ≈ 5.5774 feet, which is about 5 feet 6.93 inches.

How do I convert cm to feet and inches (like 5′ 7″)?

First convert centimeters to total inches: inches = cm ÷ 2.54. Then take the whole feet as floor(inches ÷ 12) and use the remainder as inches. Example: 170 cm → 170 ÷ 2.54 ≈ 66.9291 in → 5 feet and 6.9291 inches.

Is 1 ft = 30.48 cm exact?

Yes. By definition, 1 inch = 2.54 cm exactly and 1 foot = 12 inches, so 1 ft = 12 × 2.54 = 30.48 cm exactly.

Why do my results differ slightly from other sites?

Minor differences usually come from rounding rules. This tool displays 5 decimals for visibility but uses exact relationships under the hood.

Can I use this for human height, furniture sizing, and drawings?

Absolutely. Converting cm → ft is common for height charts, furniture dimensions, and mixed-unit technical drawings.

How many feet is 100 cm?

100 ÷ 30.48 ≈ 3.28084 feet (about 3′ 3.37″).

How many feet is 200 cm?

200 ÷ 30.48 ≈ 6.56168 feet (about 6′ 6.74″).

How precise should I be when converting to feet?

For everyday use, 2–3 decimals or feet+inches is fine. For technical work, match your instrument precision and keep significant figures consistent.

Tips for Working with Feet

For height and décor, feet + inches (e.g., 5′ 6.9″) are easier to visualize for many users.
When collaborating internationally, state units clearly (cm vs ft/in) and include the exact factor (30.48).
Round sensibly: everyday work rarely needs more than 2–3 decimals or 1/4″ precision.
