# Beats-per-minute calculator

### BPM parameters

• Beats-per-minute: `128` BPM
• Beats-per-second: `2.1333` Hz
• Length of 1 beat: `0.4688` second = 469 msec
• Length of 1 bar (4 beats): `1.875` second
• ### Loop & song length

These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
1 beat =469ms =2.13Hz
2 beats =938ms =1.06Hz
3 beats =1.41sec =0.71Hz
4 beats =1.88sec =0.53Hz
6 beats =2.81sec =0.36Hz
7 beats =3.28sec =0.3Hz
8 beats =3.75sec =0.27Hz
10 beats =4.69sec =0.21Hz
12 beats =5.63sec =0.18Hz
16 beats =7.5sec =0.13Hz
24 beats =11.25sec =0.09Hz
32 beats =15sec =0.07Hz
These are the lengths of multiple bars/measures (handy for estimating the length of a song).
2 bars =3.8 sec
4 bars =7.5 sec
8 bars =15 sec
16 bars =30 sec
24 bars =45 sec
32 bars =60 sec
40 bars =75 sec
48 bars =90 sec
60 bars =112.5 sec
80 bars =150 sec
100 bars =187.5 sec
120 bars =225 sec

### Fractions → millisecs

• 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)
