One inch is approximately 2.5cm so as there are 10 mm in a cm there are approx 25mm in an inch. However there are 12 inches in a foot, 36 inches in a yard, 39 inches in a metre. From this you can see that 1000mm = 39 inches therefore we can say more accurately that 1 inch = 1000 / 39 = 25.641 mm (to 3dp).

1 inch = 2.54 cm = 25.4 mm
To convert from inch to mm, simply multiply by 25.4 and vice versa for the other way round.. =)

one inch = 2.5 cm. 10 mm per cm., so 25 mm per inch.

Exactly 25.4mm in an inch
Used to be an approximation but a few years back they (whoever 'they' are) rounded it off to make exact conversions simpler.
