Type a value in Celsius and get the answer in Fahrenheit instantly — or convert the other way. Temperature conversion is offset-based, not a simple multiplication: the converter applies the exact formula rather than a rough factor.
The US uses Fahrenheit for weather and cooking; most of the world uses Celsius. The formula is °F = °C × 9/5 + 32 — a multiplication plus an offset, which is why the converter (not mental math) is the reliable path.
