# Beats-per-minute calculator

### BPM parameters

• Beats-per-minute: `60` BPM
• Beats-per-second: `1` Hz
• Length of 1 beat: `1` second = 1000 msec
• Length of 1 bar (4 beats): `4` second
• ### Loop & song length

These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
1 beat =1000ms =1Hz
2 beats =2sec =0.5Hz
3 beats =3sec =0.33Hz
4 beats =4sec =0.25Hz
6 beats =6sec =0.17Hz
7 beats =7sec =0.14Hz
8 beats =8sec =0.13Hz
10 beats =10sec =0.1Hz
12 beats =12sec =0.08Hz
16 beats =16sec =0.06Hz
24 beats =24sec =0.04Hz
32 beats =32sec =0.03Hz
These are the lengths of multiple bars/measures (handy for estimating the length of a song).
2 bars =8 sec
4 bars =16 sec
8 bars =32 sec
16 bars =64 sec
24 bars =96 sec
32 bars =128 sec
40 bars =160 sec
48 bars =192 sec
60 bars =240 sec
80 bars =320 sec
100 bars =400 sec
120 bars =480 sec

### Fractions → millisecs

These are some common fractions (handy for setting delays and modulation parameters)

### How to use this page

• If you have a 135 BPM song and you want a phase modulation of 4 beats: that is 1.778 sec (BEATS)
• If you have a 98 BPM song in a measure of 3/4, and you want to know how long 32 bars is: 58.78 sec (BARS)
• If you have a 128 BPM song and you want an audio delay of 2/3 of a beat: this is 313 ms (FRACTIONS)
