1 inch is exactly 2.54 cm 2.54 cm = 1 in.

In July 1959, the yard was redefined to be exactly 0.9144 meters which meant the the inch became 25.4 cm. Prior to that time, the American inch and UK inch were about 3.7 millionths of an inch different from each other. The new standard is approximately mid way between the old UK and US inch.
