What gas mark is 180°C?

180°C is gas mark 4, the common "moderate oven" setting for cakes and roasts. 200°C is gas mark 6 and 220°C is gas mark 7 on the conventional Regulo scale.

How do I convert Celsius to Fahrenheit for the oven?

Use °F = (°C × 9/5) + 32. For example 180°C = 356°F and 200°C = 392°F. The converter does this instantly along with the fan and gas-mark equivalents.

Is anything I type uploaded?

No. The oven temperature converter runs entirely in your browser. The temperature you enter is converted locally and never sent to a server.

Oven Temperature Converter

Convert oven temperatures between °C, °F, fan and gas mark.

Free oven temperature converter — switch between Fahrenheit, Celsius, fan/convection Celsius and UK gas marks for any recipe. Runs entirely in your browser; nothing is uploaded.

How do I convert a fan oven temperature?

Set a fan oven about 20°C lower than a conventional recipe temperature for the same result. So a recipe at 180°C conventional becomes 160°C fan. The converter shows the fan figure automatically.

The Oven Temperature Converter switches a recipe’s oven temperature between Fahrenheit, conventional Celsius, fan/convection Celsius and UK gas marks — so a US recipe in °F, a European one in °C and a British one in gas marks all become usable on your oven.

Conversions it covers

°C ↔ °F: °F = (°C × 9/5) + 32
Conventional → fan: subtract ~20°C (fan ovens cook hotter for the same dial setting, so recipes lower the temperature)
°C → gas mark: mapped to the conventional Regulo scale

Quick reference

Conventional °C	Fahrenheit	Fan °C	Gas mark
150	300	130	2
180	356	160	4
200	392	180	6
220	428	200	7
