Celsius to Fahrenheit
Celsius sets 0° at water's freezing point and 100° at its boiling point at sea level, the standard scale in most of the world. Fahrenheit sets 32° at water's freezing point and 212° at its boiling point, still used for everyday temperatures in the US. 1 °C equals 33.8 °F, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to temperature, measured here against temperature's base unit (°C) — every other temperature unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
°F = °C × 33.8
°C = °F × ≈-17.2222
Worked example: 5 °C × 33.8 = 41 °F.
