Centimeters and inches belong to two different measurement systems — metric and imperial. They meet constantly in real life: clothing sizes, height on forms, TV and laptop screens. This converter gives you inches and feet together, because English speakers usually say height as "5 foot 8", not "68 inches".

The cm to inches formula

1 inch = 2.54 centimeters exactly — no approximation, this is the official definition since 1959. So inches = cm ÷ 2.54, and cm = inches × 2.54. For example, 170 cm = 170 ÷ 2.54 ≈ 66.93 inches.

Converting to feet and inches

One foot equals 12 inches or 30.48 cm. To express 170 cm the American way: 66.93 inches ÷ 12 = 5 feet with 6.93 inches left over — so 5'8". The converter shows feet alongside inches so you never need the two-step math.

Common heights at a glance

160 cm ≈ 5'3" · 165 cm ≈ 5'5" · 170 cm ≈ 5'7" · 175 cm ≈ 5'9" · 180 cm ≈ 5'11" · 185 cm ≈ 6'1". Six feet is 182.88 cm — a touch under 183.
