Enter durations as seconds, mm:ss or h:mm:ss, for example track lengths.

Average

Rows that are empty or not a valid time are ignored and outlined in red. An audio CD holds about 74 to 80 minutes; one side of an LP about 18 to 22.
How it works
Times are in base 60, which makes adding them by hand error-prone. Enter each duration and read the total and the average.
Formulas
- total = Σ ( h · 3600 + m · 60 + s )
