How does this convert oven temperatures?

Between Fahrenheit, Celsius, and gas mark using standard conversion tables.

A UK temperature scale for gas ovens, with numbered marks for temperature ranges.

Why do convection recipes need adjustment?

Convection ovens cook faster, so many recipes suggest reducing set temperature by about 25°F.

Oven Temperature Converter

Convert between Fahrenheit, Celsius, and Gas Mark oven temperatures.

What Is the Oven Temperature Converter?

Oven temperatures are labeled differently around the world — Fahrenheit in the US, Celsius in most other countries, and Gas Mark in older UK recipes. This calculator converts between all three.

Formula

°F = °C × 9/5 + 32. °C = (°F − 32) × 5/9. Gas Mark is matched to the closest standard equivalence point (e.g., Gas Mark 4 ≈ 177°C ≈ 350°F).

How to Use This Calculator

Enter the temperature value from your recipe.
Select which scale it's in: Fahrenheit, Celsius, or Gas Mark.
Click Calculate to see the equivalent in all three scales.

Worked Example

A recipe calling for 350°F converts to about 177°C, which is closest to Gas Mark 4.

Tips

Gas mark ovens don't map perfectly to exact Celsius/Fahrenheit values — when in doubt, use an oven thermometer to check actual internal temperature.
