About this calculator

Convert an oven temperature between Celsius, Fahrenheit and UK Gas Mark, so a British, American or Indian recipe works in your oven.

Fan or convection ovens run hotter: reduce the temperature by about 20°C (25°F).

How to use it

  1. Enter the temperature.
  2. Choose the unit you have.
  3. Read the other two.

The conversions

°F = °C × 9/5 + 32, and °C = (°F − 32) × 5/9. Gas Mark is a stepped scale: Mark 1 is 140°C (275°F) and each mark above adds about 14°C (25°F) up to Mark 9 at 240°C (475°F). Recipes round to the nearest 5 or 10 degrees.
