Kelvin to Rankine Converter
Convert kelvin (k) to rankine (r) with the exact temperature formula, worked examples, and a common-values table.
Exact conversion
Kelvin to rankine formula
r = k × 1.8
1 k equals 1.8 r. 10 k equals 18 r.
About these units
- k
- Kelvin, an absolute temperature scale.
- r
- Rankine, an absolute temperature scale based on Fahrenheit degrees.
Before you use the result
k 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 k converts to -72 r. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
