Dew Point 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
- This calculator uses the **Magnus Formula** approximation to solve for Dew Point ($T_d$) given Temperature ($T$) and Relative Humidity ($RH$).
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Air Temperature: 25 °C
- Relative Humidity: 50%
Expected outputs
- Dew Point: 13.8 °C
- Comfort Level: Pleasant
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
- Temperature is entered in Celsius and humidity is relative humidity.
- The dew point is calculated from the Magnus approximation.
- Dew point cannot exceed the air temperature.
Unit handling
- Air Temperature accepts values in °C.
- Relative Humidity accepts values in %.
- Dew Point is displayed in °C.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
