    Enter the temperature in degrees Rankine.

  2. 2

    Multiply the Rankine value by 5.

  3. 3

    Divide the result by 9.

  4. 4

    The quotient is the temperature in Kelvin.

rankine * 5 / 9

常见问题

What is the formula to convert Rankine to Kelvin?

K = °R × 5/9. Since both scales have the same size degree, you only need to adjust the zero point.

Why is 0 °R equal to 0 K?

Both are absolute zero, the lowest possible temperature where molecular motion stops.

Can I convert Kelvin back to Rankine?

Yes, use °R = K × 9/5. The conversion is reversible.

Tips

  • Remember that the Rankine and Kelvin scales have the same degree size, so the conversion is a simple scaling factor.
  • Use absolute zero (0 °R = 0 K) as a reference point for sanity checks.
  • For quick mental estimates, multiply Rankine by 0.5556 (which is 5/9).
  • Double-check your input: Rankine is an absolute scale, so negative values are not physically meaningful.

Common Mistakes to Avoid

  • Forgetting to multiply by 5/9 and instead using a different factor.
  • Confusing Rankine with Fahrenheit; Rankine is an absolute scale, Fahrenheit is not.
  • Using the formula in the wrong direction (e.g., multiplying by 9/5 instead of 5/9).

假设与限制

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
