The calculator multiplies the number of measures by the time signature numerator to get total beats. It then adjusts for the denominator by converting to quarter-note equivalents. Finally, it divides the total quarter notes by the BPM and multiplies by 60 to get seconds, which are displayed as minutes and seconds.
BPM stands for beats per minute. It measures the tempo or speed of a song. For example, 120 BPM means the song has 120 beats in one minute, or 2 beats per second.
The time signature's denominator affects beat length. The numerator tells how many beats per measure. A 4/4 song at 120 BPM will be twice as long as a 4/8 song with the same number of measures, because eighth notes are half the length of quarter notes.
This calculator assumes constant tempo throughout the song. If your DAW shows a different duration, check for tempo changes, fermatas (holds), ritardandos (slowing), or accelerandos (speeding up) that would change the actual time.
Calculate each section separately at its own BPM and number of measures, then add the durations together. For example, a 16-measure intro at 100 BPM plus a 32-measure verse at 110 BPM would be calculated as two separate runs.
A pickup measure (anacrusis) is an incomplete measure at the beginning of a song. Count it as a fractional measure — if it has 2 beats out of 4, count it as 0.5 measures.
