How do I convert feet and inches to cm?
A foot is exactly 12 inches, and an inch is exactly 2.54 cm, so a foot is exactly 30.48 cm. For a height given in feet and inches:
cm = (feet × 12 + inches) × 2.54
Worked examples
- 5 ft 7 in: (5 × 12 + 7) × 2.54 = 67 × 2.54 = 170.18 cm
- 5 ft 0 in: 60 × 2.54 = 152.4 cm
- 6 ft: 72 × 2.54 = 182.88 cm
- 5 ft 3 in: 63 × 2.54 = 160.02 cm
Why this matters in India
Most people in India know their height in feet and inches, but official forms often ask for centimetres. Physical standards for police, armed forces and other recruitment are published in cm, and so are medical records, passport and visa forms in many countries, and BMI calculations. A mistake of one inch is 2.54 cm, which can matter when a recruitment notice sets a minimum like 157 cm or 165 cm. Always use the measured height from the official test, not an estimate.
Common mistakes
- 5.7 feet is not 5 feet 7 inches. 5.7 feet as a decimal is 5 feet 8.4 inches (0.7 × 12 = 8.4), which is 173.7 cm. The calculator uses separate feet and inches boxes to avoid this mix-up.
- Rounding. Round only at the end. 5 ft 7 in is 170.18 cm, often written as 170 cm.
How do I convert cm back to feet and inches?
Divide the centimetres by 2.54 to get total inches, then divide by 12. The whole number is feet and the remainder is inches. For 165 cm: 165 ÷ 2.54 = 64.96 inches, which is 5 feet and 4.96 inches, so about 5 ft 5 in. Use the swap button above, or the CM to Inches converter, for this.
