Temperature Conversion Formula
Convert from Celsius to Fahrenheit:
°F = °C × 1.8 + 32
Example:
170°C = 170 × 1.8 + 32 = 338°F
190°C = 374°F
Convert from Celsius to Fahrenheit:
°F = °C × 1.8 + 32
Example:
170°C = 170 × 1.8 + 32 = 338°F
190°C = 374°F
170°C is commonly used for baking and roasting:
Note: Preheat the oven and use an oven thermometer to calibrate the temperature.
170°C is ideal for:
Tip: Air fryers are hotter than conventional ovens; adjust the temperature and cooking time accordingly.
170°C in a convection oven is suitable for:
Precautions: Convection ovens may require a 5-10°C lower temperature setting.

Fan Oven: Fan ovens circulate heat through the air, so temperatures are typically about 20°C lower than conventional ovens. For example, a conventional oven set to 190°C should be set to 170°C for a fan oven.
Gas Mark: Gas ovens are marked in 25°F increments and are typically used in the UK, Ireland, and some Commonwealth countries.
Calibration: If your oven temperature is inaccurate, it is recommended that you use an oven thermometer for calibration.
Cooking Time: Fan ovens cook faster due to the even distribution of heat, so you may need to lower the temperature or shorten the cooking time appropriately.
