Oven temperature converter
Convert oven settings between Fahrenheit, Celsius, and standard gas mark references.
What this calculator covers
Use this oven temperature converter to translate a recipe instruction between Fahrenheit, Celsius, and gas mark without flipping between charts.
Frequently asked questions
- What temperature range do gas marks cover?
- The standard gas mark scale runs from mark 1 (275°F / 135°C) through mark 9 (475°F / 245°C), with each mark representing a 25°F step. Temperatures outside this range have no corresponding gas mark, and the calculator will indicate when a Fahrenheit or Celsius input falls outside the standard ladder.
- What is a moderate oven in Fahrenheit and Celsius?
- A moderate oven is commonly described as around 350°F or 175°C. Many baking recipes that call for a moderate oven use this range, though some recipes use 325°F or 375°F depending on the desired browning rate.
- Why does the gas mark converter show "approx." for some temperatures?
- Most recipe temperatures in Fahrenheit or Celsius do not land exactly on one of the standard 25°F gas mark steps. When that happens the calculator shows the nearest whole gas mark with an "approx." label to indicate the match is rounded.
- Do fan-assisted ovens run hotter than the set temperature?
- Fan-assisted (convection) ovens circulate air and typically cook at a higher effective temperature than the dial setting suggests. A common guideline is to reduce the set temperature by about 20°C (or roughly 25°F) compared with a conventional oven, but oven behavior varies — check your appliance manual for specific guidance.

- Gas mark
- Approx. Gas mark 4
Step-by-step solution
- 1.Normalize the starting value to Fahrenheit using the selected scale so every equivalent runs through one shared oven-temperature baseline.
- 2.Convert the Fahrenheit result to Celsius with (F - 32) × 5 / 9 to get 180°C.
- 3.Map the Fahrenheit result onto the standard gas-mark ladder to read Approx. Gas mark 4.
Walkthrough
Visual walkthrough
Oven temperature conversion works best when every input is normalized onto one shared scale, then translated into the other cooking references.
01
Read the entered oven setting
180°C
The calculator starts from the selected Fahrenheit, Celsius, or gas-mark reference.
02
Normalize to Fahrenheit
356°F
Fahrenheit acts as the shared baseline for the Celsius and gas-mark equivalents in this calculator.
03
Read the kitchen equivalents
The same oven setting is then restated as Celsius and the nearest standard gas mark when one exists.
