°C = (°F − 32) × 5/9. To go back the other way, apply the inverse formula — for example 0°F = -17.7778°C.
1 °F = -17.2222 °C; 10 °F = -12.2222 °C; 100 °F = 37.7778 °C. Use the full conversion table below for more reference values.
At −40 degrees: −40°C and −40°F are the same temperature. That is the only point where the two scales intersect, because the scales have different zero points and step sizes.
