How the conversion works
The relationship is °C = (°F − 32) × 5/9. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor.
