Tempo timing in both directions
BPM to Milliseconds Calculator
Enter a tempo to get precise note lengths, or convert a millisecond value back to BPM.

How BPM becomes milliseconds
One minute contains 60,000 milliseconds. Divide 60,000 by the BPM to find the duration of one beat, treated here as a quarter note. Multiply that duration by the beat value for longer notes, or divide it for shorter notes.
The reverse calculation uses the selected note value: BPM = 60,000 × beats represented ÷ milliseconds.
When these timings are useful
A BPM delay calculator helps set tempo-synced delay, pre-delay, release, modulation, gates, and sequencer steps. Straight, dotted, and triplet values let you match the rhythmic feel instead of using only one beat length.
Four beats also gives the duration of one 4/4 bar when the quarter note carries the beat.
Calculation scope
The page performs arithmetic in your browser and does not analyze audio. Results display two decimal places; the underlying calculation is performed before display rounding.
Time signatures can assign the beat to a note other than the quarter note. Check the tempo definition used by your score, device, or plugin before applying a value.
BPM and milliseconds FAQ
How does a milliseconds to BPM calculator work?
Select the note value represented by the duration, then divide 60,000 times that beat value by the milliseconds entered.
Is this also a BPM delay calculator?
Yes. Use the straight, dotted, or triplet result that matches the delay rhythm you want, then enter that millisecond value in your effect.
Why are the results not rounded to whole milliseconds?
Two decimal places preserve more of the calculated timing. Your hardware or software may still accept only whole milliseconds.
