## What is cm to inches?

cm to inches is the conversion of length units from cm to inches. There are exactly 2.54 centimeters in 1 inch. To convert from centimeters (cm) to inches (in) divide by 2.54.

Divide cm by 2.54

cm divided by 2.54 is inches or

cm / 2.54 = in

### Explanation:

1 inch is equal to 2.54 centimeters. For conversions of units we say that there are 2.54 centimeters per inch and write it as 2.54 cm/in. To convert from centimeters to inches, divide cm units by 2.54 cm/in. Centimeters (cm) will cancel and we are left with inches (in) units in the answer.

Example: What is 18 cm in inches?

18 cm to inches is calculated here using division:

18 cm ÷ 2.54 cm/in

Divide through and cancel cm units

18 ~~cm~~ ÷ 2.54
~~cm~~/in = 7.086614 in

18 cm = 7.086614 in

Since we are dividing by 2.54 cm/in, that is the same as multiplying by 1/(2.54 cm/in) and 1 divided by 2.54 cm/in is approximately equal to 0.3937 in/cm. Therefore, the alternative calculation for converting centimeters to inches can be performed using multiplication instead as follows: (notice the slightly different answer since we approximated in/cm as 0.3937)

18 cm to inches is calculated here using multiplication:

18 cm × 0.3937 in/cm

Multiply through and cancel cm units

18
× 0.3937 in/*cm* = 7.0866 in
*cm*

18 cm = 7.0866 in

### Convert Metric units to Imperial and US units
