How long is a beat at 85 BPM?

At 85 BPM a quarter note lasts 705.88 ms (60,000 ÷ 85). An eighth is 352.94 ms, a dotted eighth 529.41 ms, a sixteenth 176.47 ms and a sixteenth triplet 117.65 ms. A one-beat LFO runs at 1.42 Hz, and one 4/4 bar lasts 2,823.53 ms.

quarter note (ms) = 60 000 ÷ BPM;  note = quarter × q;
dotted = note × 1.5;  triplet = note × 2/3;  rate (Hz) = 1000 ÷ ms;
bar = quarter × beats × 4 ÷ unit;  samples = seconds × sample rate

This page uses the same method as the BPM to MS Calculator, which explains each term and assumption in full.

Worked example

A boom bap beat at 85 BPM with a short slap on the vocal

1Quarter note: 60,000 ÷ 85 = 705.88 ms
2Eighth note: 705.88 ÷ 2 = 352.94 ms; dotted: 352.94 × 1.5 = 529.41 ms
3Sixteenth triplet: 176.47 × 2/3 = 117.65 ms
4LFO once per beat: 1000 ÷ 705.88 = 1.42 Hz
5Hall reverb: pre-delay 1/64 = 44.12 ms, decay 5,602.94 ms to end on 2 bars

At 85 BPM: 705.88 ms quarter, 529.41 ms dotted eighth, 117.65 ms sixteenth triplet, 1.42 Hz per beat.

Frequently asked questions

What is the dotted eighth delay time at 85 BPM?

529.41 ms. An eighth note at 85 BPM is 352.94 ms, and a dot adds half again: 352.94 × 1.5 = 529.41 ms. The dotted quarter is twice that, 1,058.82 ms, and the plain quarter 705.88 ms.

What music is made at 85 BPM?

Mostly boom bap and classic East Coast hip-hop. 85 BPM sits in the classic boom bap range of roughly 85 to 95 BPM. It does not divide into round numbers, which is exactly why a calculator helps: a quarter note is 705.88 ms, and rounding to 700 ms drifts a full sixteenth note out within about 30 repeats.

What is 85 BPM in half time and double time?

Half time is 42.5 BPM, with a 1,411.76 ms quarter note; double time is 170 BPM, with a 352.94 ms quarter note. A delay set to a quarter note at 85 BPM is a half note in double time and an eighth note in half time, so it stays in sync either way.
