UnitConCelsius to Fahrenheit Converter
Convert Celsius to Fahrenheit for weather forecasts, cooking temperatures, and body temperature readings. This is the most searched temperature conversion worldwide, bridging the metric standard used globally and the Fahrenheit scale used in the US.
Formula
Multiply Celsius by 9/5 (1.8) and add 32 to get Fahrenheit. To reverse, subtract 32 from Fahrenheit and multiply by 5/9.

About these units
Celsius
The Celsius scale was proposed by Swedish astronomer Anders Celsius in 1742, originally with 0° at the boiling point of water and 100° at freezing — later reversed by Carl Linnaeus. It became the international standard temperature scale used in the SI system.
Fahrenheit
Daniel Gabriel Fahrenheit, a German physicist, introduced his scale in 1724, setting 0° at the freezing point of a brine solution and 96° at body temperature. The modern Fahrenheit scale places water's freezing point at 32°F and boiling at 212°F.
Frequently asked questions
37 × 1.8 + 32 = 98.6°F, which is normal human body temperature.
-40°. Both scales coincide at -40 degrees.
0°C = 32°F, the freezing point of water.
Double the Celsius temperature and add 30 for a quick estimate. For example, 20°C ≈ 40 + 30 = 70°F (actual: 68°F).
