68 °F
20 °C = 68 °F
°F = °C × 9/5 + 32
°C to °F formula
°F = °C × 9/5 + 32
Reverse: °C = (°F − 32) × 5/9
Celsius and Fahrenheit use different zero points and degree sizes, so temperature conversion needs both multiplication and an offset. Multiply Celsius by 9/5, then add 32. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at standard atmospheric pressure. The two scales have the same numerical value at −40.
