Velocity - Angular Converter
Convert angular velocity between radians and revolutions per second, minute and hour.
Written by Rahman · Last reviewed
Quick answer
Angular velocity measures rotation rate. The SI unit is the radian per second: one revolution per minute is 0.10472 rad/s and one revolution per second is 2π, or 6.2832 rad/s. Multiplying angular velocity by the radius gives the linear speed at that radius.
| Radian per second (rad/s) | 1 |
| Radian per minute (rad/min) | 59.99999988 |
| Radian per hour (rad/h) | 3599.999971 |
| Degree per second (°/s) | 57.29577958 |
| Degree per minute (°/min) | 3437.746873 |
| Revolution per second (rev/s) | 0.1591549431 |
| Revolution per minute (rpm) | 9.549296587 |
| Revolution per hour (rev/h) | 572.9577794 |
About the Velocity - Angular Converter
Angular velocity measures how fast something rotates: the angle swept per unit of time. It is expressed in radians or revolutions per second, minute or hour.
This converter is used in mechanics, motors and machinery, where rotational speed such as RPM must be compared with radians per second.
Frequently Asked Questions
How do I convert RPM to radians per second?
⌄
Multiply revolutions per minute by 0.10472 (which is 2π divided by 60).
What does RPM mean?
⌄
RPM stands for revolutions per minute: the number of complete turns made each minute.
How many radians are in one revolution?
⌄
One full revolution equals 2π radians, approximately 6.2832 radians.
