0 Celsius to Fahrenheit (0 °C to °F)

Formula and worked answer

°F = °C × 1.8 + 32

Substituting 0 for °C: 0 × 1.8 + 32 = 32 °F. The factor 1.8 comes from the exact international definition of the degree Celsius relative to the degree Fahrenheit, so this answer is precise rather than rounded.

What does 0 Celsius represent?

0 degrees Celsius (32 °F) is the freezing point of water at standard atmospheric pressure and the lower anchor of Anders Celsius's original 1742 scale. Converted to Fahrenheit it is exactly 32 °F, which is the figure printed on every US thermometer's "freezing" tick mark and the threshold US weather services use for ice and frost warnings. The two anchors of 0 °C and 100 °C define the Celsius scale by international agreement, so the conversion to 32 °F and 212 °F is exact rather than approximate. For travellers reading metric weather forecasts in Europe or Canada, 0 °C is the figure that translates "snow" or "ice" into the imperial-system 32 °F US drivers learn from school.
