About this tool
Celsius and Fahrenheit are offset scales, not just different sizes: water freezes at 0 °C but 32 °F, and boils at 100 °C but 212 °F. The formula °F = °C × 9/5 + 32 handles both the different step size and the different zero point.
Landmarks worth memorising: −40 is the same on both scales, normal body temperature is 37 °C = 98.6 °F, and a hot oven at 200 °C is 392 °F.
