  • How to Convert RPM to Surface Speed Sciencing

    Multiply the circumference by the object s angular speed measured in rpm. For example if it rotates at 400 rpm 87.98 400 = 35 192. This is the object s surface speed measured in inches per minute. Divide this answer by 63 360 which is the number of inches in a mile 35 192 ÷ 63 360 = 0.555. This is the surface speed in miles per minute.
