How many degrees Celsius are in 1 degree Fahrenheit?

1 degree Fahrenheit equals -17.2222 °C.

How do I convert degrees Celsius back to degrees Fahrenheit?

Use the reverse converter: 1 degree Celsius equals 33.8 °F.

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

To convert degrees Fahrenheit to degrees Celsius, use the formula °C = (°F − 32) × 5/9.

°C = (°F − 32) × 5/9

375 °F → °C = (°F − 32) × 5/9 → 190.56 °C

Kelvin and Rankine start at absolute zero, so negative values are physically impossible.

Degree Fahrenheit (°F): Used for everyday temperatures in the US and a few other countries. Proposed by Daniel Fahrenheit in 1724; water freezes at 32 °F and boils at 212 °F.
Degree Celsius (°C): The temperature scale used by most countries and in science. Defined by Anders Celsius in 1742; 0 °C is water's freezing point and 100 °C its boiling point at sea level.
