At 128 BPM, one beat (a quarter note) is 468.75 ms.
- Eighth note
- 234.38 ms
- Sixteenth note
- 117.19 ms
- Dotted quarter
- 703.13 ms
- Triplet quarter
- 312.50 ms
- BPM, reversed
- 128 BPM
Every subdivision scales the same quarter-note ms value. Reversed, that ms value read as one beat is exactly the BPM you entered.
Straight
| Note value | Ms | Hz | |
|---|---|---|---|
| 1 bar (4 beats) | 1875.00 ms | 0.53 Hz | |
| Half note (2 beats) | 937.50 ms | 1.07 Hz | |
| Quarter note (1 beat) | 468.75 ms | 2.13 Hz | |
| 8th note | 234.38 ms | 4.27 Hz | |
| 16th note | 117.19 ms | 8.53 Hz | |
| 32nd note | 58.59 ms | 17.07 Hz |
Dotted
| Note value | Ms | Hz | |
|---|---|---|---|
| Dotted half | 1406.25 ms | 0.71 Hz | |
| Dotted quarter | 703.13 ms | 1.42 Hz | |
| Dotted 8th | 351.56 ms | 2.84 Hz | |
| Dotted 16th | 175.78 ms | 5.69 Hz |
Triplet

Why it matters
Why Converting BPM to Milliseconds Matters
When setting delay times, reverb pre-delays, sidechain release times, or LFO rates in your DAW or DJ software, you need timing values in milliseconds that match your track's tempo. A delay set to the exact ms value of a dotted 8th note at 128 BPM creates that classic "ping-pong" effect that sits perfectly in the groove. Use this chart as a quick reference while producing or preparing effects for a live set.
Formula
BPM to Milliseconds Formula
The base formula is simple: ms = 60,000 ÷ BPM. This gives you the duration of one quarter note (one beat) in milliseconds. From there, derive other note values:
| Note value | Derivation |
|---|---|
| Whole note | ms × 4 |
| Half note | ms × 2 |
| Quarter note | ms (base value) |
| Eighth note | ms ÷ 2 |
| Sixteenth note | ms ÷ 4 |
| Dotted values | base × 1.5 |
| Triplet values | base × 2/3 |
For bar-level timing (transitions and cue points), see the beats-to-time calculator. To tempo-match two tracks, use the pitch & tempo calculator.

- Tool pages are built from reusable page logic, internal DJ reference data, and visible on-page calculations. Programmatic reference pages are generated from structured data rather than hand-written one by one.
BPM, key, and genre labels can vary by edit, remaster, detection engine, and DJ software. Use these pages as a practical mixing reference, then verify important tracks in your own library.
