Convert Celsius to Fahrenheit and Fahrenheit to Celsius instantly. Change either value and the matching temperature updates automatically.
The converter uses the standard formulas °F = (°C × 9/5) + 32 and °C = (°F − 32) × 5/9. It is useful for weather, cooking, science work, travel, and any time a temperature appears in an unfamiliar scale.
20°C × 9 ÷ 5 + 32 = 68°F. In reverse, (68°F − 32) × 5 ÷ 9 = 20°C.
Multiply the Celsius value by 9/5, then add 32.
20°C equals 68°F.
The two scales are equal at -40 degrees.
