250°F = 120°C Oven (100°C Fan / Gas Mark ½)
250°F equals 120°C on a standard oven dial (exact 121.1°C), 100°C (225°F) in a fan-assisted convection oven, and UK Gas Mark ½, providing very slow / low domestic oven heat ideal for gentle slow-braising and slow-drying meringues.
250°F converts to 121°C (dial setting 120°C). This low, gentle heat prevents egg proteins in meringues or custards from curdling and dries out delicate confections without browning.
