Vibration is measured by speed and expressed in the form of RPM, which stands for Rotations Per Minute.


The greater a vibrator’s speed, the higher number of RPMs it will have and the stronger vibrations it will create. A less potential for impact a vibrator has a lower number of RPMs. Because all vibrators have multiple rotations per second (let alone minute), using RPMs to describe speed and intensity isn’t the most convenient way to communicate the strength of a sex toy (especially because the meaning of any particular number varies from culture to culture). As a user-friendly, objective alternative to the RPM system, developed a more understandable system for regular people to understand how vibrators work.
