What this temperature conversion is for

Use this page when a measurement is written in degrees Rankine and the next step needs degrees Celsius. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Change degree Rankine to Celsius first, then into degree Celsius. Celsius and kelvin use the same size step. Fahrenheit and Rankine use a smaller step: nine of those degrees fit in five Celsius degrees. °C = (°F − 32) × 5/9. K = °C + 273.15. °R = (°F + 459.67).

A worked example

528 degrees Rankine are 20.18333333 degrees Celsius. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.
