- Degrees Celsius.
- r
- Rankine, an absolute temperature scale based on Fahrenheit degrees.
Before you use the result
c to r context and checks
- Best use
- Use temperature conversions for weather, cooking, lab notes, HVAC, and equipment settings.
- Common mistake
- Temperature scales use offsets, so Celsius to Fahrenheit is not only multiplication. Temperature differences use different handling.
- Precision note
- Avoid rounding before applying an offset formula because the zero point and interval size both affect the result.
Example check: -40 c converts to 419.67 r. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
