Temperature Converter 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
- Unlike other units, temperature conversion involves addition/subtraction, not just multiplication. * **C to F:** (C × 1.8) + 32 * **F to C:** (F - 32) / 1.8 * **C to K:** C + 273.15 * **K to C:** K - 273.15
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Temperature: 0
- From Scale: Celsius (°C)
- To Scale: Fahrenheit (°F)
Expected outputs
- Converted Value: 32
- Details: 0°C = 32.00°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
- Temperature conversions use exact scale formulas with Celsius as the intermediate reference.
- The calculator converts absolute temperature values, not temperature differences or rates of change.
- Kelvin values below absolute zero are mathematically convertible here but are not physically meaningful.
Unit handling
- Temperature accepts numeric values.
- From Scale accepts one of the configured options.
- To Scale accepts one of the configured options.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
