How many millimeters are in one inch?

Explanation:
Converting inches to millimeters uses the exact factor that one inch equals 25.4 millimeters. This comes from the fact that one inch is 2.54 centimeters, and since 1 centimeter is 10 millimeters, 2.54 cm equals 25.4 mm. So the correct value is 25.4 mm per inch. The other numbers mix units or drop the decimal: 25 is missing the .4, 2.54 is in centimeters, not millimeters, and 26.4 is just a mistaken value.
