Frequently asked
- What is 350°F in Celsius?
- 350°F = 177°C, using the exact formula °C = (°F − 32) × 5/9. Most recipes round this to 180°C.
- What is Gas Mark 4?
- Gas Mark 4 = 350°F = 180°C, from the standard UK gas-mark reference table.
- How do I adjust a recipe for a fan (convection) oven?
- Common guidance is to reduce a conventional temperature by about 20°C (roughly 25–35°F), or shorten the time. Ovens vary, so use an oven thermometer for anything temperature-sensitive.
