Converting celsius to fahrenheit
This converter changes a value in celsius (°C) into fahrenheit (°F). One celsius equals 33.8 °F. The Celsius and Fahrenheit scales meet at −40°, where both read the same number. Water freezes at 0 °C / 32 °F and boils at 100 °C / 212 °F at sea level. The conversion runs entirely in your browser — enter a value and the result updates instantly, in either direction.
Formula
°F = °C × 1.8 + 32
Example
Convert 25 °C to °F: 25 × 1.8 + 32 = 77 °F.
