🔥 Fahrenheit to Gas Mark Converter
Instantly convert oven temperatures from Fahrenheit (°F) to the UK Gas Mark scale. Perfect for baking and roasting with British recipes. Includes descriptions like moderate, hot, and very hot.
What Is the Gas Mark Scale?
The Gas Mark is a temperature scale used on gas ovens and cookers in the United Kingdom, Ireland, and some Commonwealth countries. It was introduced in the 1940s and has become a standard for British recipes.
Key characteristics of the Gas Mark scale:
- Gas Mark 1 = 275 °F (135 °C) , the base reference point.
- Each step increases by approximately 25 °F (14 °C).
- Gas Mark 4 (350 °F / 177 °C) is the most common baking temperature.
- Quarter marks (¼ and ½) are used for very low temperatures.
- Descriptions like "moderate," "hot," and "very hot" accompany each mark.
The Gas Mark scale is still widely used today, especially in older British cookbooks and recipes from the UK, Ireland, Australia, and New Zealand.
How to Convert Fahrenheit to Gas Mark
The approximate formula to convert Fahrenheit to Gas Mark is:
Gas Mark ≈ (°F − 250) ÷ 25
For temperatures between 275 °F and 475 °F
This formula provides a good approximation because Gas Mark 1 = 275 °F, and each mark adds ~25 °F.
For example, to convert 350 °F to Gas Mark:
Gas Mark = (350 − 250) ÷ 25
Gas Mark = 100 ÷ 25
Gas Mark = 4
350 °F is the most common baking temperature and corresponds to Gas Mark 4.
