Height Converter — Free Online Tool
Height is written in feet and inches in India, the US and the UK, but in centimetres on most official forms and in medical records, which is why this height converter exists. Choose Ft+In to CM and enter the feet and inches to get an exact centimetre value, or switch to CM to Ft+In to turn a metric height into feet and inches. For example, 5 feet 11 inches converts to 180.34 cm, and 170 cm is about 5 feet 7 inches. The conversion uses the exact factors of 30.48 centimetres per foot and 2.54 centimetres per inch, so rounding errors stay tiny. It is useful when filling in matrimonial profiles, job and exam applications, passport or visa forms, fitness apps, clothing size guides and the BMI calculator, all of which can ask for height in a different unit from the one you know. The result appears as a clear sentence you can copy straight into a form. Because the tool only does the arithmetic, it runs entirely in your browser with no data saved and no registration needed. Use the Unit Converter for other length conversions like metres, miles and yards, and the BMI Calculator to turn height and weight into a health indicator.

Frequently Asked Questions
How do I convert feet and inches to centimetres?
Multiply the feet by 30.48 and the inches by 2.54, then add them. For 5 ft 8 in: 5 × 30.48 + 8 × 2.54 = 172.72 cm.
How do I convert centimetres to feet and inches?
Divide the centimetres by 30.48 to get feet. The whole number is the feet and the decimal part multiplied by 12 gives the inches. 170 cm is 5 ft 6.9 in.
How tall is 5 feet 5 inches in cm?
5 ft 5 in equals 165.1 cm (5 × 30.48 + 5 × 2.54). Use the Ft+In → CM mode to check any other height.
Why does the converted height show decimals?
Inches and centimetres do not divide into one another evenly, so the tool shows precise decimals. Round to the nearest centimetre or half inch for official forms.
Can I convert height in metres?
Enter the value in centimetres, so 1.75 m becomes 175 cm. For other length units use the Unit Converter.
