Instead of stopping the count at 1 minute, you may want to count for 2 or 3 minutes and then divide the count by the number of minutes to get the RPM if the object rotates slowly. Well also show you how the cross-sectional area calculator [], (Hz \times 60 \times 2) \div number \; of \; poles = \text {no-load} \; RPM. We measure the frequency of a rotation in revolutions per minute (abbreviated as RPM or rpm). Use this page to learn how to convert between RPM and hertz. But what is RPM, exactly? Frequency = (RPM X Line Count/60) Use this formula when line count of the encoder and RPM are known. Definition of 1 feet per minute 1 ft / 60 s = 30.48 cm / 60 s. The speed with which the body moves 1 foot (or 30.48 centimetres) in 1 minute..Compared to metre per second, feet per minute is smaller unit. For our example muzzle velocity of 2000 feet per second, multiplying by 12 gives 2000 x 12 = 24,000 inches per second.
