How to convert feet and inches to centimeters

One foot equals 12 inches, and one inch equals 2.54 centimeters. Therefore, convert the feet portion to inches, add the remaining inches, and multiply the total by 2.54.

Centimeters = (feet × 12 + inches) × 2.54

Example: 5 feet 10 inches

5 × 12 + 10 = 70 inches. Then 70 × 2.54 = 177.8 cm.

How to convert centimeters to feet and inches

Divide centimeters by 2.54 to get total inches. Divide total inches by 12 to get feet and the remaining inches.

For example, 170 cm ÷ 2.54 ≈ 66.93 inches. That is 5 feet with about 6.93 inches, or approximately 5'6.9".

Feet versus decimal feet

5'6" is not the same as 5.6 feet. Six inches is half a foot, so 5 feet 6 inches equals 5.5 decimal feet. This distinction is a common source of conversion errors.

Common mistakes

  • Treating inches as decimal fractions of a foot.
  • Forgetting that a foot contains 12 inches.
  • Rounding too early.
  • Confusing centimeters with meters.
