Jul 18, 2019· Centrifuges may be classified based on maximum speeds, measured as revolutions per minute (RPM). Speeds range from 0-7,500 RPM for low-speed centrifuges, all the way to 20,000 RPM or higher. The following formula is used to convert RPM to RCF, where R is the rotor radius (cm) and S is the speed (RPM): g = (1.118 x 10-5) R S 2 . Centrifuge
