About Oven Temperature Converter
Recipes from different regions describe oven temperature in different systems — American recipes use Fahrenheit, most of the world uses Celsius, and older British recipes often specify a 'gas mark' instead of a numeric temperature — so following a foreign recipe accurately means converting between all three.
This tool converts a Fahrenheit temperature to its Celsius equivalent and finds the closest matching UK gas mark, along with a plain-language description (like 'Moderate' or 'Hot') that's often used alongside the numeric gas mark in older recipes.
A full reference table below the converter lists every standard gas mark from 1 to 9 with its Fahrenheit and Celsius equivalents and description, so you can look up any oven setting at a glance without recalculating each time.
How it works
- Enter a temperature in Fahrenheit. Type your oven temperature in degrees Fahrenheit.
- See the conversions. View the equivalent Celsius temperature and nearest UK gas mark.
- Check the reference table. Browse the full gas mark table for quick lookups.
