Questions

How do I convert HH:MM:SS into seconds?

The tool multiplies hours by 3600 and minutes by 60, then adds seconds. For example, 01:02:03 becomes 3723.

What does a single value such as 2 mean here?

The first component represents hours. Enter 00:00:02 for two seconds, rather than a single 2.

Can I convert several durations at once?

Yes. Enter one colon-separated duration per line, with at most three components. An invalid component produces an error that identifies the line.
