BPM to Milliseconds
Convert a tempo in BPM into delay times for whole, half, quarter and eighth notes.
About BPM to Milliseconds
Sixty seconds of milliseconds divided by BPM gives the beat duration; dividing again by the note value snaps the tempo to a musical grid. Delay pedals, DJ loops and DAW plugins all live on beat-synced time, so converting BPM to milliseconds keeps effects locked to the tempo.
Formula
BPM to Milliseconds
Delay ms = 60 x 1000 / (BPM x note divisions)
- note divisions
- How many equal notes divide one beat (whole=1, quarter=4, eighth=8)
Worked example
With the default values below, BPM to Milliseconds returns Delay Time of 1,250. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is BPM to Milliseconds calculated?
Delay ms = 60 x 1000 / (BPM x note divisions) Sixty seconds of milliseconds divided by BPM gives the beat duration; dividing again by the note value snaps the tempo to a musical grid.
Why does BPM to Milliseconds matter?
Delay pedals, DJ loops and DAW plugins all live on beat-synced time, so converting BPM to milliseconds keeps effects locked to the tempo.
What values do I need to enter?
This calculator takes 2 inputs: Tempo, Note value. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
