When this helps
Timelines in editors are often labeled in seconds while humans quote decimal minutes (such as 3.75 min). Dividing by 60 is the reliable bridge; multiplying by 60 brings minute estimates back onto the second-accurate scale your waveform or lap timer uses.
Formulas
- Minutes from seconds: minutes = seconds ÷ 60
- Seconds from minutes: seconds = minutes × 60
