Why use this calculator
Recipes from different regions use different temperature scales. UK recipes often use Gas Marks, European recipes use Celsius, and American recipes use Fahrenheit. This converter handles all three instantly.
How to use it
Enter the temperature value and select the scale it is in. The calculator converts to all other scales and provides a heat description such as moderate or hot.
The formula
°C = (°F - 32) * 5/9; °F = °C * 9/5 + 32; Gas Mark mapped to nearest standard value
Worked examples
350°F to Celsius and Gas Mark
350°F = 177°C = Gas Mark 4 (Moderate)
Gas Mark 6 to Fahrenheit
Gas Mark 6 = 400°F = 204°C (Hot)
When people use it
- Following British recipes that use Gas Mark settings
- Converting European Celsius recipes for American ovens
- Setting the correct temperature on unfamiliar oven models
- Professional kitchen standardisation across equipment
Tips
- Most baking happens between Gas Mark 3-6 (325-400°F / 163-204°C)
- Always preheat your oven for at least 10-15 minutes before baking
- Oven thermometers are more accurate than built-in dials and cost very little
- Fan-forced ovens typically run 20°C (35°F) hotter than conventional ovens
Questions people ask
- What is Gas Mark?
- Gas Mark is a temperature scale used on gas ovens in the UK and some Commonwealth countries. Each mark corresponds to a 25°F increment starting from Gas Mark 1 at 275°F.
- Should I adjust for fan-forced ovens?
- Yes, reduce the temperature by about 20°C (35°F) when using a fan-forced or convection oven compared to a conventional oven setting.
