For example: 25°C × 1.8 + 32 = 77°F

Key Temperature Reference Points

Water freezes — 0°C = 32°F

Cold winter day — 10°C = 50°F

Mild room temperature — 20°C = 68°F

Warm summer day — 25°C = 77°F

Hot day — 30°C = 86°F

Human body temperature — 37°C = 98.6°F

Very hot / heat wave — 40°C = 104°F

Water boils — 100°C = 212°F

Oven moderate baking — 180°C = 356°F
