How many degrees Fahrenheit are in 1 degree Celsius?

1 degree Celsius equals 33.8 °F.

How do I convert degrees Fahrenheit back to degrees Celsius?

Use the reverse converter: 1 degree Fahrenheit equals -17.2222 °C.

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

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

°F = °C × 9/5 + 32

18 °C → °F = °C × 9/5 + 32 → 64.4 °F

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

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.
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.
