  0.4 of an inch Answer   There are 2.54 centimeters in 1 inch, so 1 centimeter is 0.394 inches.
To find out how many centimeters in inches, multiply by the conversion factor or use the converter. 1 Inch = 2.54 Centimeters There are 2.54 centimeters in an inch, because one foot is defined as 30.48 centimeters and there are 12 inches in a foot, that makes 30.48 / 12 = 2.54 cm in an inch. For example, to find out how many centimeters there are on a 12 inch ruler, multiply the inch value by the conversion factor, that makes 12 in * 2.54 cm = 30.48 centimeters on a 12 inch ruler. Inch is an imperial and US customary length unit. There are 12 inches in a foot, 36 inches in a yard and 63360 inches in a mile. The abbreviation is in.
