Pace Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Pace = Total Time / Distance. Speed = Distance / Total Time.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Hours: 0
- Minutes: 30
- Seconds: 0
- Distance: 3.1 miles
Expected outputs
- Pace per Mile: 9:41
- Speed: 6.2 mph
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- The result uses average pace over the full distance rather than showing split-by-split variation.
- Distance and time are assumed to be measured accurately and in consistent units.
- Terrain, hills, weather, and stop time can make real race pacing feel very different from the average result.
Unit handling
- Hours accepts numeric values.
- Minutes accepts numeric values.
- Seconds accepts numeric values.
- Distance accepts values in miles.
- Speed is displayed in mph.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
