Re: seat post and handlebar stem
Remember the number 25.4 Divide millimeters by 25.4 to get inches. Multiply inches by 25.4 to get millimeters. Remember, inches must be converted to decimals. Example.....
1 1/8" = 1.125 inches 1.125 times 25.4 = 28.575 28.575 millimeters
33mm divided by 25.4 = 1.2992125984251968503937007874016 for all intents and purposes 1.3 inches
