The Centimeters to Inches Converter converts centimeters to inches using the exact factor 1 cm = 0.393701 inches (or equivalently, divide by 2.54). This converter is indispensable for anyone working with international product specifications, body measurements, or engineering drawings that use different unit systems.
Our converter provides results in both decimal inches and fractional inches (1/16ths), making it useful for woodworking, sewing, and other crafts where fractional inches are standard. The conversion is exact because the inch is defined as precisely 2.54 centimeters.
Understanding centimeters-to-inches conversion is important for online shopping (international sizing), medical records (height measurement), and manufacturing (tolerances and specifications).
The formula: inches = centimeters ÷ 2.54. For fractional inches, the result is rounded to the nearest 1/16th of an inch. Since 1 inch = 2.54 cm exactly, this is a mathematically exact conversion.
Common conversions: 1 cm ≈ 0.394 in, 10 cm ≈ 3.937 in, 30 cm ≈ 11.811 in, 100 cm ≈ 39.370 in.

Divide the centimeter value by 2.54. For example, 10 cm ÷ 2.54 = 3.937 inches.
1 centimeter = 0.3937 inches, or approximately 25/64 of an inch.
170 cm = 66.93 inches, which is about 5 feet 7 inches.
Convert to decimal inches first (÷ 2.54), then round to the nearest fraction (1/8, 1/16, or 1/32 depending on needed precision).
150 cm = 59.06 inches = 4 feet 11.06 inches, or approximately 4'11".
Yes, since 1 inch is defined as exactly 2.54 cm, the inverse conversion is also exact.
Divide by 2.5 for a fast estimate (about 2% off). For better accuracy, multiply by 0.4.
12 inches (1 foot) = 30.48 cm exactly.
100 cm = 39.37 inches. This is just slightly longer than a yardstick (36 inches).
Most countries use the metric system (cm). The US, Myanmar, and Liberia are the only countries that haven't officially adopted metric as their primary system.
