Frequently asked questions
What is 1 fahrenheit in celsius?
1 fahrenheit is -17.22 °C. Temperature scales have different zero points, so you cannot multiply by that figure for other values. Use °C = (°F − 32) × 5 ÷ 9. instead.
How do I convert fahrenheit to celsius?
Use °C = (°F − 32) × 5 ÷ 9.. For example, 37 fahrenheit gives 2.78 °C. Enter your own value above and the converter does the arithmetic for you.
How do I convert celsius back to fahrenheit?
Use the Celsius to Fahrenheit converter, or invert the factor by dividing instead of multiplying.
Is this conversion exact?
Temperature scales differ by an offset as well as a ratio, which is why you cannot convert them by multiplying alone.
