Oven Temperature Converter

Convert between Celsius, Fahrenheit, and gas marks.

Free to use, no sign-up required. Oven Temperature Converter is one of 198 tools built into Xenition, alongside a chat that can use them for you.

Converts oven temperatures between Celsius, Fahrenheit and UK gas marks, and names the traditional cookbook term such as moderate or hot. It is for recipes written for a different oven.

How to use Oven Temperature Converter

  1. Type the temperature, or the gas mark number, in the Value box.
  2. Choose what you typed with the °C, °F or Gas buttons.
  3. Read the three boxes: °C, °F and Gas Mark, with the old cookbook term under the gas mark.

How it works

Fahrenheit becomes Celsius by (°F − 32) ÷ 1.8, and Celsius becomes Fahrenheit by × 1.8 + 32; both display as whole degrees. Gas marks come from the standard UK table (¼ = 110 °C, ½ = 120, 1 = 140, 2 = 150, 3 = 170, 4 = 180, 5 = 190, 6 = 200, 7 = 220, 8 = 230, 9 = 240, plus 10 = 260), and the tool shows the mark whose temperature is nearest.

Example

An American recipe at 350 °F is 177 °C, gas mark 4, which the tool labels Moderate. 200 °C is 392 °F and gas mark 6, Moderately hot.

Questions about Oven Temperature Converter

Should I lower the temperature for a fan oven?

Usually yes. Fan (convection) ovens cook hotter for the same setting, so most recipes suggest about 20 °C (25 °F) lower. The conversions here are for conventional ovens.

What is a moderate oven?

In older cookbooks, a moderate oven is around 180 °C (350 °F), gas mark 4. Hot is about 220 °C, and a very cool oven is below 140 °C.
