Conversion notes
- Kelvin cannot go below 0 because it is an absolute scale.
- Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level—use these to sanity-check results.
- Avoid rounding mid-conversion when precision matters; copy the 2-decimal output instead.
FAQ
- Why do Kelvin values include decimals?
- Kelvin is directly tied to Celsius with a 273.15 offset. Decimal precision preserves accuracy from the source measurement.
