Formula

How to convert bars and beats to time

Multiply the number of bars by the beats in each bar to find the total beats. Dividing that total by beats per minute gives minutes; multiplying by 60 gives seconds. This is useful for planning arrangement sections, cue lengths and set timings.

seconds = bars × beats per bar × 60 ÷ BPM

  1. 01

    Use the beats-per-bar field for the top number of the time signature when the BPM counts that beat unit.

  2. 02

    Calculate individual sections to plan intros, drops, ad breaks or fixed-length cues.

  3. 03

    The result assumes a constant tempo with no pauses, ramps or tempo changes.

Worked example

Example: 16 bars at 120 BPM

Sixteen bars of 4/4 contain 64 quarter-note beats. At 120 beats per minute, 64 beats last 32 seconds, so a 16-bar section runs for 0:32.

Good to know

Assumptions and limits

  • The tempo stays constant for the full section.
  • Beats per bar matches the beat unit counted by the BPM value.
  • Count-ins, pauses, fermatas and tempo ramps are not included.
Quick answers

Frequently asked questions

How long are 16 bars at 120 BPM?

In 4/4, 16 bars at 120 BPM last 32 seconds.

How do I calculate a 3/4 section?

Set beats per bar to 3 when the BPM represents quarter-note beats.

Does this handle tempo changes?

Calculate each constant-tempo section separately, then add the durations together.
