°C → °R°R = (°C + 273.15) × 9/5
Exact anchors0 °C = 491.67 °R
°R → °C°C = °R × 5/9 − 273.15
iTemperature conversions are affine (scale + offset), not a single multiply. Absolute zero is 0 K = −273.15 °C = −459.67 °F = 0 °R.

How to use

1

Choose °C → °R or °R → °C

Use the tabs to switch direction. Forward mode needs celsius; reverse uses the opposite unit.

2

Enter the temperature

Type a signed value in the active unit field.

3

Convert and read the result

Use Convert or let the result update automatically.
