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.

Step-by-step solution

  1. 1.Normalize the starting value to Fahrenheit using the selected scale so every equivalent runs through one shared oven-temperature baseline.
  2. 2.Convert the Fahrenheit result to Celsius with (F - 32) × 5 / 9 to get 180°C.
  3. 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.

  1. 01

    Read the entered oven setting

    180°C

    The calculator starts from the selected Fahrenheit, Celsius, or gas-mark reference.

  2. 02

    Normalize to Fahrenheit

    356°F

    Fahrenheit acts as the shared baseline for the Celsius and gas-mark equivalents in this calculator.

  3. 03

    Read the kitchen equivalents

    The same oven setting is then restated as Celsius and the nearest standard gas mark when one exists.
