Is 180°C exactly 350°F?

No. 180°C is exactly 356°F; 350°F is about 176.67°C. A recipe may supply a rounded alternate setting.

Should I reduce the setting for convection?

Check the recipe, selected oven mode, and appliance manual. Some appliances convert settings automatically; applying a second reduction would change the intended setting.

How to Measure

Read the unit on the recipe and appliance. Use a recipe’s explicitly supplied alternate setting when available; otherwise calculate the conversion and choose an available dial setting. Consult the appliance manual for convection modes.

Notes

These are calculated temperatures: °F = °C × 1.8 + 32. Rounded recipe settings are distinct from exact unit arithmetic. This chart does not provide a verified gas-mark mapping or a universal fan-oven adjustment.
