Centimeter (cm) is a metric unit of length equal to one-hundredth of a meter (1 cm = 0.01 m). It is part of the International System of Units (SI) and is the standard unit used in most countries for measuring everyday lengths — from human height and clothing sizes to screen dimensions and furniture.
Inch (in) is an imperial unit of length equal to exactly 2.54 centimeters. It is widely used in the United States and partially in the UK and Canada. Inches are commonly seen in TV and monitor screen sizes, tire dimensions, clothing measurements, and human height in the American system.

There are exactly 2.54 centimeters in one inch. So 1 in = 2.54 cm.
The formula is: in = cm ÷ 2.54. Simply divide any centimeter value by 2.54 to get the result in inches.
1 cm = 0.3937 inches. Since an inch is 2.54 cm, one centimeter is slightly less than half an inch.
5 cm = 1.969 inches, approximately 2 inches. Calculation: 5 ÷ 2.54 = 1.969 in.
10 cm = 3.937 inches, just under 4 inches. This is roughly the width of a typical smartphone screen.
30 cm = 11.811 inches. This is the length of a standard 30 cm ruler, which is just under 12 inches (1 foot).
100 cm = 39.37 inches. Since 1 meter = 100 cm, this also means 1 meter ≈ 39.37 inches.
First divide cm by 2.54 to get total inches. Then divide by 12 to get feet, and the remainder is inches. For example: 175 cm ÷ 2.54 = 68.9 in → 68.9 ÷ 12 = 5 feet 8.9 inches (5'9").
An inch is bigger than a centimeter. One inch equals 2.54 cm — so an inch is about 2.5 times larger than a centimeter.
