Celsius to Fahrenheit
Multiply by 9/5 (or 1.8) and add 32. For example, 37°C × 1.8 + 32 = 98.6°F (human body temperature). The two scales meet at -40° — both -40°C and -40°F are the same temperature.
FAQ
°F = (°C × 9/5) + 32. Example: 37°C = 98.6°F.
The lowest possible temperature: 0K = -273.15°C = -459.67°F. All molecular motion stops.
