Height Converter: Feet + Inches to CM
Convert human height both ways: feet and inches to centimeters, and centimeters back to feet and inches. Type it the way people say it, like 5'10", and get an instant answer plus a BMI healthy-weight reference and a full conversion chart.
Healthy weight range for this height
Convert a height above to see the weight range for BMI 18.5 to 24.9.
BMI (body mass index) is a screening tool, not a medical diagnosis. It does not account for muscle mass, bone density, age, or pregnancy. Talk to a clinician for personal advice.
Looking for a different converter?
- Generic length (any object), feet to cm: use the ft to cm converter.
- Quick one-way feet+inches to cm: use feet and inches to cm.
- Predict a child's adult height from parents: use the height calculator.
Scope of this tool: human height only, two-way conversion (ft+in to cm and cm to ft+in), free-text input like 5'10", a full conversion chart, and a BMI healthy-weight reference.

Worked examples
A note on growth chart percentiles
This converter changes height units only. A growth chart percentile (for example "75th percentile for a 10-year-old boy") depends on the child's exact age, sex, and the CDC or WHO reference tables, so no unit converter can compute it honestly. Convert the height here, then look it up on the official CDC/WHO growth charts or ask your pediatrician.
Frequently asked questions
How do I convert 5'10" to centimeters?
First add up the inches: 5 x 12 + 10 = 70 inches. Then multiply by 2.54 cm per inch: 70 x 2.54 = 177.8 cm.
What is the formula for feet and inches to cm?
cm = (feet x 12 + inches) x 2.54. One inch is exactly 2.54 cm by definition, and one foot is 12 inches.
How do I convert cm to feet and inches?
Divide the cm value by 2.54 to get total inches, then split into feet and leftover inches. Example: 175 cm / 2.54 = 68.9 in, which is 5 ft 8.9 in.
Can I type 5'10" directly into the converter?
Yes. The input accepts 5'10", 5 ft 10 in, 70 in, 5.5 ft and similar formats, then converts instantly.
What is 5'10" in cm?
5'10" is 177.8 cm.
What is 170 cm in feet and inches?
170 cm is 5 ft 6.9 in (170 / 2.54 = 66.9 inches).
What is 6 feet in cm?
6 ft = 72 in = 182.88 cm, shown as 182.9 cm when rounded to one decimal.
What is a healthy weight for my height?
A BMI of 18.5 to 24.9 is the commonly used healthy range. At 5'10" (177.8 cm) that is 58.5 to 78.7 kg (128.9 to 173.5 lb). BMI is a screening tool, not a medical diagnosis.
Does this tool calculate growth chart percentiles?
No. Percentiles need age, sex, and CDC or WHO reference tables. This tool converts height units only and does not estimate percentiles.
Is 1 inch exactly 2.54 cm?
Yes. The inch has been defined as exactly 2.54 cm since the 1959 international yard agreement, so the conversion has no measurement error.
How is this different from a generic ft to cm converter?
This converter is built for human height: it works both ways, parses 5'10"-style input, shows a BMI healthy weight range, and includes a height conversion chart. For generic lengths, use a plain ft to cm converter.
How precise is the result?
The math is exact; results are shown rounded to one decimal (0.1 cm is about 0.04 inch), which is finer than a tape measure can read on a person.
Can I convert inches only, for example 70 in to cm?
Yes. Type 70 in (or just 70) in the feet+inches panel: 70 x 2.54 = 177.8 cm.
