Converting centimeters to feet takes seconds with the right tool. Whether you’re checking a person’s height, sizing furniture, or comparing metric and imperial measurements, this free online cm to ft calculator gives you an instant, accurate result.

Quick Definition: A centimeter (cm) is a metric unit of length equal to one-hundredth of a meter in the International System of Units (SI). A foot (ft) is a unit of length in the imperial and US customary system equal to 30.48 centimeters or 12 inches.

How the Centimeter-to-Foot Conversion Works

One foot equals exactly 30.48 centimeters. That fixed relationship makes the conversion straightforward — you divide your cm value by 30.48 to get feet as a decimal, or split the result into feet and inches for height measurements.

The standard formula to convert centimeter to foot:

ft = cm / 30.48

To convert feet to cm, simply reverse it:

cm = ft x 30.48

Since one foot contains 12 inches, you can also express the decimal remainder as inches by multiplying it by 12. For example, 180cm equals 5 feet and 10.87 inches — a common reference for height converter use cases.

Limitations: This formula works perfectly for standard length units. However, if you need to measure height in fractional feet like 5’11 with rounding, the decimal output may vary slightly depending on how the tool rounds. Always confirm unit of length requirements for official documents or medical records.

Seeing It in Action: Converting 170 cm to Feet

Say you want to know a person’s height of 170 cm in feet and inches.

• Step 1: Divide by 30.48 → 170 / 30.48 = 5.5774 ft
• Step 2: The whole number is 5 feet
• Step 3: Take the decimal (0.5774) and multiply by 12 → 0.5774 x 12 = 6.93 inches
• Result: 170 cm = 5 feet 6.93 inches

This same logic applies whether you’re converting mm, meters, or yards into compatible length units — the base relationship between cm and feet stays constant at 2.54 cm per inch and 0.3048 meters per foot.

Need to go the other way? The feet to inches calculator handles that split instantly, so you can move between imperial units without recalculating manually.
