A centimeter (cm) is a metric unit of length that represents one hundredth of a meter. It is widely used for measuring small distances and lengths.
For example, when measuring the length of a pencil, you can use a ruler marked in centimeters. Place one end of the ruler at the starting point of the pencil and read the measurement at the other end. If the measurement reads 15 cm, it indicates that the length of the pencil is 15 centimeters from the starting point to the end.
Inches are a unit of length commonly utilized in the Imperial system and the United States customary system. One inch is equivalent to 1/12th of a foot or approximately 2.54 centimeters.
For instance, when measuring the length of a small object like a pencil using a ruler marked in inches, you would place one end of the ruler at the starting point of the pencil and read the measurement at the other end. If the measurement reads 6 inches, it indicates that the length of the pencil from the starting point to the end is 6 inches.
1cm = (1/2.54)″ = 0.3937007874″
Distance d in inches (″) is equal to distance d in centimeters (cm) that is divided by 2.54:
d(″) = d(cm) / 2.54
For Example
Convert 100 cm to inches:
d(″) = 100cm / 2.54 = 39.371″

To convert inches to centimeters, you can use the conversion factor: 1 inch = 2.54 centimeters. Simply multiply the number of inches by 2.54 to get the equivalent length in centimeters.
To convert centimeters to inches, you can divide the number of centimeters by 2.54. Since 1 inch is equal to 2.54 centimeters, dividing the length in centimeters by 2.54 will give you the equivalent length in inches.
No, 1 inch is not equal to 3 centimeters. The correct conversion factor is 1 inch = 2.54 centimeters. So, 1 inch is equal to 2.54 centimeters.
The length of 1 inch on a finger is the same as any other 1-inch measurement. It is equal to 2.54 centimeters.
To convert 40 centimeters to inches, you divide 40 by 2.54 (the conversion factor). The result is approximately 15.75 inches.
To convert 90 centimeters to inches, divide 90 by 2.54. The result is approximately 35.43 inches.
