Frequently asked questions
What is the formula to convert C to F?
Multiply by 9/5 (1.8) and add 32. For example 20 C x 1.8 + 32 = 68 F.
At what temperature are Celsius and Fahrenheit equal?
At -40 degrees, where -40 C equals -40 F.
What is a quick mental trick?
Double the Celsius figure and add 30: 20 C becomes about 70 F. It is within a degree or two for everyday weather.
What is 1 fahrenheit in celsius?
1 fahrenheit = -17.2222 celsius (°F to °C).
What is the formula to convert °F to °C?
°C = (°F − 32) × 5/9. For example, 98.6 °F = 37 °C.
How do I convert °C back to °F?
