85 BPM in Milliseconds: Delay Times and Note Lengths
At 85 BPM one beat (a quarter note) lasts 705.882 ms and one bar of 4/4 lasts 2.824 seconds. Below are the delay times for every note value, the same notes in Hz, bar and phrase lengths, samples per beat and the genres that typically sit at this tempo.
85 BPM at a glance
- One beat at 85 BPM lasts about 705.88 ms (60,000 divided by 85), an eighth note about 352.94 ms and a dotted eighth about 529.41 ms.
- A beat here is not a whole number of milliseconds. The nearest tempo where it is: 80 BPM, with 750 ms per beat.
- A beat is 31,129.412 samples at 44.1 kHz and 33,882.353 samples at 48 kHz, neither a whole number, so sample accurate loop points round slightly at both rates.
- A 4 bar phrase in 4/4 takes about 11.294 seconds, and 3 minutes of music at this tempo holds 63.75 bars of 4/4.
- Going from 85 to 86 BPM shortens each beat by 8.208 ms, about 1.16% of the beat.
- An LFO synced to quarter notes runs at about 1.417 Hz; synced to whole bars of 4/4 it runs at about 0.3542 Hz.
