How to use it
- Type a number. A dot or a comma works as the decimal separator.
- Choose the unit you have and the unit you need. The swap button reverses them.
- The table shows the same value in all common units at once.
Conversion factors
Every unit is converted through radians per second, using 1 turn = 2π rad = 360°.
| Unit | In rad/s |
|---|---|
| 1 rpm | 2π ÷ 60 ≈ 0.104720 |
| 1 rev/s | 2π ≈ 6.283185 |
| 1 °/s | π ÷ 180 ≈ 0.017453 |
| 1 rev/h | 2π ÷ 3600 ≈ 0.001745 |
Worked example
A motor turning at 3,000 rpm makes 3,000 ÷ 60 = 50 turns per second, which is 50 × 2π ≈ 314.16 rad/s or 18,000 degrees per second.
Quick reference
- 60 rpm = 1 rev/s = 2π rad/s ≈ 6.283 rad/s
- 1 rad/s ≈ 9.549 rpm ≈ 57.30 °/s
- Frequency in hertz equals revolutions per second
