Oven Temperature Converter
Convert oven temperatures between Fahrenheit, Celsius and Gas Mark instantly. Perfect for baking, cooking, and following recipes from around the world.
How to Convert Oven Temperatures
Converting oven temperatures is essential when following recipes from different countries. Here are the key formulas:
- Fahrenheit to Celsius: (°F − 32) × 5/9 = °C
- Celsius to Fahrenheit: (°C × 9/5) + 32 = °F
- Celsius to Gas Mark: Gas Mark = (°C × 9 ÷ 125) − 2.5 (approximately)
- Gas Mark to Celsius: °C = (Gas Mark + 2.5) × 125 ÷ 9
The Gas Mark system is primarily used in the UK. Each gas mark corresponds to a specific temperature range:
- Gas Mark ¼: 107°C (225°F) — Very cool
- Gas Mark 1: 135°C (275°F) — Cool
- Gas Mark 2: 150°C (300°F) — Warm
- Gas Mark 3: 160°C (325°F) — Moderate
- Gas Mark 4: 180°C (350°F) — Moderate hot
- Gas Mark 5: 190°C (375°F) — Fairly hot
- Gas Mark 6: 200°C (400°F) — Hot
- Gas Mark 7: 220°C (425°F) — Very hot
- Gas Mark 8: 230°C (450°F) — Very hot
- Gas Mark 9: 240°C (475°F) — Extremely hot
Why Use This Converter?
Our oven temperature converter helps you follow recipes from any country. Whether you're baking a cake from a UK cookbook (Gas Mark), following a US recipe (Fahrenheit), or using a European recipe (Celsius), this tool gives you instant, accurate conversions.
Tips for Accurate Oven Temperatures
- Use an oven thermometer: Many ovens are not perfectly calibrated. An oven thermometer gives you the true temperature.
- Preheat properly: Always preheat your oven for at least 10-15 minutes before baking.
- Fan-forced ovens: If using a fan-forced (convection) oven, reduce the temperature by 20°C (25°F) or use the manufacturer's guidelines.
- Gas ovens: Gas ovens often have hot spots. Rotate your baking trays halfway through cooking for even results.
How Accurate Is This Converter?
This converter uses the exact mathematical formulas for temperature conversion. Gas Mark values are based on the standard UK conversion table, which is accurate for all common oven temperatures. Results are displayed with up to 2 decimal places for precision.
Frequently Asked Questions
To convert Fahrenheit to Celsius: subtract 32 from the Fahrenheit temperature, then multiply by 5/9. For example: 350°F − 32 = 318 × 5/9 = 176.6°C (often rounded to 180°C).
Gas Mark 4 is approximately 180°C (356°F). This is one of the most common oven temperatures for baking cakes and cookies.
180°C is equal to 356°F. This is approximately Gas Mark 4 and is the standard temperature for many baked goods.
The Gas Mark system is a temperature scale used on older gas ovens, primarily in the UK. Each number corresponds to a specific temperature range. Gas Mark 1 is about 135°C (275°F), and Gas Mark 9 is about 240°C (475°F).
This converter uses the exact mathematical formulas for temperature conversion. For Gas Mark, it uses the standard UK conversion table which is accurate for all common oven temperatures.
A moderate oven is typically 180°C (350°F, Gas Mark 4). This is the most common baking temperature used in recipes.
