Musical and acoustic relationship
Formula
ms per beat = 60000 ÷ BPM= 500
Note
This result is a simplified model: it applies the displayed standard formula to the values you entered, assuming twelve-tone equal temperament, a speed of sound of 343 m/s in dry air at 20 °C, an ideal free field with no reflections or air absorption, purely resistive speaker loads and Sabine's diffuse-field assumption. Real rooms, instruments, codecs and amplifiers depart from these idealisations, so measure with proper instruments for critical work.

How does BPM convert to a millisecond duration?+
One quarter note at a given BPM lasts 60,000 / BPM milliseconds, since BPM defines how many quarter-note beats occur in 60,000 milliseconds (one minute). At 120 BPM, for example, a quarter note is exactly 500 ms.
How are other note values like eighth or sixteenth notes derived?+
Each note value is a fraction or multiple of the quarter note duration: an eighth note is half the quarter-note ms value, a sixteenth is a quarter, and a half note is double. The calculator applies these ratios automatically once it has the base quarter-note duration.
Why do delay and reverb plugins need this calculation?+
Delay times synced to tempo need to land exactly on musical subdivisions, so producers convert BPM to milliseconds to dial in delays that repeat in time with the beat rather than drifting off-grid. The same math sets LFO rates and gate/trance-gate effects to the track's tempo.
What's a dotted or triplet note value in this context?+
A dotted note is 1.5 times its plain duration, and a triplet note is 2/3 of its plain duration, since three triplets must fit in the space of two plain notes of the same value. These modifiers are commonly needed for tempo-synced delay times like 'dotted eighth' delay.
Does the time signature affect the millisecond value of a beat?+
No, BPM-to-ms conversion is defined relative to the quarter note regardless of time signature, so 120 BPM gives a 500 ms quarter note whether the track is in 4/4 or 3/4. The time signature affects how beats group into bars, not the duration of a single beat.
