BPM to Milliseconds
Convert any tempo to note lengths in milliseconds — for delay times, LFO rates, pre-delay, and sample editing. One beat at a given BPM is 60,000 ÷ BPM milliseconds.
| Note value | Milliseconds |
|---|---|
| Whole note | 2000 ms |
| Half note | 1000 ms |
| Quarter note | 500 ms |
| Dotted eighth | 375 ms |
| Eighth note | 250 ms |
| Eighth triplet | 166.7 ms |
| Sixteenth note | 125 ms |
Delay time chart, 40–240 BPM
The dotted eighth is the classic rhythmic delay (think pulsing synth and guitar lines); eighth and quarter delays sit inside the groove; triplets swing against it. The same numbers work for tempo-synced LFO rates and reverb pre-delay.

The formula
One quarter-note beat is 60,000 ÷ BPM milliseconds. From there: halve it for eighths, quarter it for sixteenths, multiply by 0.75 for a dotted eighth, and divide by 3 for eighth-note triplets. A full 4/4 bar is four beats — 240,000 ÷ BPM.
Don't know the song's tempo yet? Find it with the tap tempo tool first. And if you need to hear a tempo instead of calculate it, every linked BPM in the chart plays a click track — or build your own with the free click track generator — sections, time signatures, subdivisions, and a WAV download.
Frequently asked questions
How do I convert BPM to milliseconds?
Divide 60,000 by the BPM. At 120 BPM one beat is 60,000 ÷ 120 = 500 ms. For an eighth note halve it (250 ms), for a sixteenth quarter it (125 ms), and for a dotted eighth multiply the beat by 0.75 (375 ms).
What delay time should I use for my song?
Start with a dotted-eighth delay — the classic rhythmic setting — or an eighth note for tighter slapback-style echoes. Match the table row to your song's BPM, or type the exact tempo into the calculator above.
Do these numbers work for LFO rates and pre-delay too?
Yes. Any time-based effect can be tempo-synced with the same values: set an LFO cycle to a bar or beat length, or sync reverb pre-delay to a short note value — a thirty-second or sixty-fourth note keeps it in the typical 10–120 ms range at most tempos.
What if my tempo isn't in the chart?
Use the calculator at the top — it takes any tempo from 10 to 400 BPM and updates all note values instantly. The chart lists 5-BPM steps for quick reference.
