Oven Temperature Converter
Oven temperatures can be expressed in Celsius (°C), Fahrenheit (°F), or UK Gas Mark — and every recipe seems to use a different scale. This converter instantly translates any oven temperature between all three systems, so you can follow any recipe without guesswork, whether it comes from a British cookbook using Gas Mark 6, an American recipe calling for 350 °F, or a European one listing 180 °C.
Gas Mark is a scale used mainly in the United Kingdom and Ireland. Each mark corresponds to a specific Celsius and Fahrenheit temperature, and also carries a descriptive label such as 'moderate', 'hot', or 'very hot'. This converter uses the standard table to map between Gas Mark and the metric/imperial scales, and also displays the descriptive label so you know at a glance what kind of heat you are working with.
How it works
Celsius to Fahrenheit: °F = °C × 9/5 + 32. Fahrenheit to Celsius: °C = (°F − 32) × 5/9. Gas Mark to Celsius: lookup via the standard UK Gas Mark table (e.g. Gas Mark 4 ≈ 180 °C / 356 °F — Moderate).
Use cases
- Converting British cookbook Gas Mark settings to Celsius or Fahrenheit
- Adapting American recipes that list oven temperature in °F for European ovens
- Finding the correct Gas Mark for a recipe that only gives a Celsius temperature
- Checking whether your oven setting matches the 'moderate', 'hot', or 'very hot' description in a recipe
- Teaching the relationship between Celsius, Fahrenheit, and Gas Mark to students learning to cook
Frequently asked questions
What is 350°F in Celsius?
350°F equals about 177°C, using the formula °C = (°F − 32) × 5/9. In practice most recipes round this to 175°C or 180°C. It is one of the most common baking temperatures and corresponds to roughly Gas Mark 4.
What is Gas Mark 6 in Celsius and Fahrenheit?
Gas Mark 6 is 200°C, which equals 400°F, and is labelled a 'hot' oven on the standard UK scale. Each Gas Mark step of one is about 14°C (25°F). This setting is common for roasting and for crisp pastry.
How do I convert Celsius to Fahrenheit for oven temperatures?
Use °F = °C × 9/5 + 32. For example, 180°C becomes 180 × 9/5 + 32 = 356°F. To go the other way, use °C = (°F − 32) × 5/9. The converter applies these formulas automatically across all three scales.
What is 180°C in Fahrenheit and Gas Mark?
180°C equals 356°F and corresponds to Gas Mark 4, described as a 'moderate' oven. This is the standard temperature for many cakes, biscuits, and general baking. Recipes often list 350°F as the nearest rounded equivalent.
What temperature is a moderate oven?
A moderate oven is around 180°C (350°F), or Gas Mark 4. Cooler settings such as 150°C are called 'slow' or 'low', while hotter settings above 220°C are 'hot' to 'very hot'. The converter shows the descriptive label alongside every conversion.
