Tempo calculator
BPM to milliseconds calculator
Turn a tempo into delay and note times. At 120 BPM, a quarter note lasts 500 ms and an eighth note lasts 250 ms.
500 msQuarter-note duration
Half note1000 ms
Eighth note250 ms
Sixteenth note125 ms
Dotted eighth375 ms
Eighth triplet166.67 ms
Thirty-second note62.5 ms
Calculation: 60,000 ÷ BPM for one quarter note. Enter 1–999 BPM.
How to convert BPM to milliseconds
A quarter note lasts 60,000 ÷ BPM milliseconds. The other values multiply that duration by their rhythmic length. The calculation is general; a hardware delay may use its own display or clock behavior.
| BPM | Quarter | Eighth | Dotted eighth | Sixteenth |
|---|---|---|---|---|
| 60 | 1000 | 500 | 750 | 250 |
| 90 | 666.67 | 333.33 | 500 | 166.67 |
| 120 | 500 | 250 | 375 | 125 |
| 128 | 468.75 | 234.38 | 351.56 | 117.19 |
| 140 | 428.57 | 214.29 | 321.43 | 107.14 |
Does this send MIDI clock?
No. This calculator gives you a duration to enter in an effect or compare with a tempo. It does not send clock or change a device’s sync settings.
For sync problems, choose a device in clock and start/stop troubleshooting. You can also convert a MIDI note number to frequency.
