Frequently Asked Questions

Why would I need to convert training times to seconds?

Seconds are the common denominator for calculating pace, splits, or averages across mixed time formats — spreadsheets and pace calculators often need a single unit to do math correctly.

Does this handle time-of-day conversion (like AM/PM)?

No — this converts durations (elapsed time), not clock times. For time-of-day math, a different tool is needed.
