Gas Mark is a temperature scale used on gas ovens in the UK and some Commonwealth countries. Gas Mark 1 = 275°F = 140°C. Each mark adds 25°F.
The UK officially switched to Celsius in the 1960s. However, many older recipes and gas ovens still reference Gas Mark.
Enter a temperature in Fahrenheit, Celsius, or Gas Mark. The calculator converts between all three and shows common cooking temperature references.
°F = °C × 9/5 + 32. °C = (°F – 32) × 5/9. Gas Mark = (°F – 250) / 25 (approximate for common baking temps).
350°F = 177°C = Gas Mark 4. 400°F = 204°C = Gas Mark 6. 450°F = 232°C = Gas Mark 8. Boiling point: 212°F = 100°C.
Oven temperatures can vary ±25°F from the dial setting — use an oven thermometer for accuracy. For convection ovens, reduce the recipe temperature by 25°F. Always preheat for at least 15 minutes.
