How to convert 0 °C to Fahrenheit
0 × 1.8 = 0
0 + 32 = 32 °F
Multiply by 9/5 (1.8) because each Celsius degree spans 1.8 Fahrenheit degrees, then add 32 because water freezes at 32 °F rather than 0. Since 0 is a multiple of 5, the result is a whole number.
Estimate it in your head
Double it and add 30: 0 × 2 + 30 = 30 °F, which is 2 degrees low.
0 °C: where the Celsius scale starts
The Celsius scale is built around water: 0 °C is where pure water freezes at standard sea-level pressure and 100 °C is roughly where it boils. (Anders Celsius’s original 1742 scale actually ran the other way, with 0 for boiling.) That makes 0 °C equal to 32 °F, and each Celsius degree 1.8 times as large as a Fahrenheit degree.
