Inch (abbreviation: in): is a unit of length in the (British) imperial and United States customary systems of measurement now formally equal to 1/36 yard but usually taken as 1/12 of a foot.

Millimeter (abbreviation: mm): is a unit of length in the SI metric system, equal to one thousandth of a metre. Therefore, there are thousand millimetres in a metre and ten millimetres in a centimetre.


How to Convert Inches to Millimeters

Example: How many millimeters are equivalent to 24.57 inches?


As;

1 inches = 25.4 millimeters

24.57 inches = Y millimeters

Assuming Y is the answer, and by criss-cross principle;

Y equals 24.57 times 25.4 over 1

(i.e.) Y = 24.57 * 25.4 / 1 = 624.078 millimeters

Answer is: 624.078 millimeters are equivalent to 24.57 inches.
