Tire Pressure Temperature 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
- Estimated PSI = starting PSI + (temperature change / 10).
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Starting Pressure: 35 PSI
- Starting Temperature: 70 °F
- New Temperature: 30 °F
Expected outputs
- Estimated New Pressure: 31 PSI
- Pressure Change: -4 PSI
- Temperature Change: -40 °F
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
- All prices, fees, rates, and vehicle assumptions are user-entered.
- Calculations run locally in your browser and are not stored by Calwarden.
- This is planning math, not financial, tax, insurance, legal, or mechanical advice.
Unit handling
- Starting Pressure accepts values in PSI.
- Starting Temperature accepts values in °F.
- New Temperature accepts values in °F.
- Estimated New Pressure is displayed in PSI.
- Pressure Change is displayed in PSI.
- Temperature Change is displayed in °F.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Input precision follows configured step values where provided.
