> The BPM calculator converts a song’s tempo into delay and reverb times in milliseconds for quarter, eighth, sixteenth, dotted and triplet notes, so effects sit in time with the music.

## Inputs

- Tempo (BPM)

## Results

- Quarter note
- Eighth note
- Sixteenth note
- Dotted eighth
- Quarter triplet
- One bar (4/4)

## Formula

```
Quarter note (ms) = 60,000 ÷ BPM
```

## Explanation

Delay set to note values locks echoes to the beat; dotted eighths are a classic guitar effect.

### How to use the BPM to Delay Time Calculator

- **Tempo**
- Want to work backwards? Type a value into **Quarter note** and **Tempo** is calculated for you.

Results update as you type, and every field accepts the units shown in its menu.

### How it works

One beat lasts 60,000 ÷ BPM milliseconds; other note values scale from that.

### What each result means

- **Quarter note** = 60000÷[Tempo]
- **Eighth note** = 30000÷[Tempo]
- **Sixteenth note** = 15000÷[Tempo]
- **Dotted eighth** = 45000÷[Tempo]
- **Quarter triplet** = 40000÷[Tempo]
- **One bar (4/4)** = 240000÷[Tempo]

### Example values

How the main result changes when **Tempo** changes and everything else stays at the example values above:

Tempo (BPM)Quarter note (ms)601,00090666.7120500150400180333.3240250

## Worked example

Inputs — Tempo: 120 BPM.

Results — **Quarter note = 500 ms**; Eighth note = 250 ms; Sixteenth note = 125 ms; Dotted eighth = 375 ms; Quarter triplet = 333.3 ms; One bar (4/4) = 2,000 ms.

## FAQ

**How do I find a song’s BPM?**
Tap along with a tap-tempo tool or count beats in 15 seconds and multiply by 4.

**Is pre-delay tied to tempo too?**
Often; short note values such as 1/64 work well.

**What formula does the BPM to Delay Time Calculator use?**
Quarter note (ms) = 60,000 ÷ BPM.

**Can I work backwards from the result?**
Yes. Type the result you want into Quarter note and the calculator finds the matching tempo.
