Formula: °F = °C × 9/5 + 32. Water freezes at 0 °C / 32 °F and boils at 100 °C / 212 °F; −40 is the same on both scales. The general Unit Converter also covers length and weight pairs.
How it works & limits
Exact arithmetic, no rounding tricks: °F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9, with Kelvin shown alongside (K = °C + 273.15). Reference points: Absolute zero −273.15 °C · Water freezes 0 °C / 32 °F · Body temperature ≈ 37 °C / 98.6 °F · Water boils 100 °C / 212 °F.
