Formula used

K = °C + 273.15 · °F = °C×9/5 + 32 · °R = °F + 459.67

Every result substitutes your values into this relation step by step above.

Assumptions

  • Anchor points are exact by definition: 0 °C = 273.15 K, °F = °C × 9/5 + 32.
  • Rankine uses the Fahrenheit degree size with a kelvin-compatible zero point.

Limitations

  • Inputs below absolute zero are rejected as physically impossible.
