How many millimeters are in 1 inch?

Explanation:
Conversions between inches and millimeters are fixed: one inch is exactly 25.4 millimeters. To convert, multiply by 25.4, so 1 inch equals 25.4 mm. Another way to see it is that 1 inch equals 2.54 centimeters, and since 1 centimeter is 10 millimeters, that also gives 25.4 millimeters. The other numbers would correspond to different fractions of an inch (for example, 20 mm is about 0.79 in, 30 mm about 1.18 in, and 15.9 mm about 0.63 in), which is why 25.4 mm is the correct value for 1 inch.
