Time Conversion Calculator
Convert Between Time Units
Understanding This Calculator
A straightforward unit converter for time values — useful for converting race splits, training log entries, or interval timings between seconds, minutes, hours, and days without manual arithmetic.
All conversions are exact (60 seconds/minute, 60 minutes/hour, 24 hours/day), so results are precise to the input value.
Seconds = value × conversion factor (60, 3600, or 86400)
- value the number you’re converting
- unit the unit you’re converting from
| From | To Seconds |
|---|---|
| 1 minute | 60 sec |
| 1 hour | 3,600 sec |
| 1 day | 86,400 sec |
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.
