°F = °C × 9/5 + 32 and K = °C + 273.15. Water freezes at 0°C (32°F) and boils at 100°C (212°F), and normal body temperature is about 37°C (98.6°F). Enter a value, choose its unit and see all three scales at once.
Useful for weather, cooking, science homework and checking fever readings from foreign thermometers.
Multiply the Celsius value by 9/5 and add 32. For example, 37°C is 98.6°F.
Subtract 32 from the Fahrenheit value and multiply by 5/9. For example, 212°F is 100°C.
0 K is absolute zero, equal to −273.15°C.
