°C = (°F − 32) × 5/9 - Put in the value: 17 degrees Fahrenheit.
- Result: -8.333333 degrees Celsius.
Degrees Fahrenheit to degrees Celsius table
| degrees Fahrenheit | degrees Celsius |
|---|---|
| 1 f | -17.222222 c |
| 2 f | -16.666667 c |
| 5 f | -15 c |
| 10 f | -12.222222 c |
| 17 f | -8.333333 c |
| 20 f | -6.666667 c |
| 50 f | 10 c |
| 100 f | 37.777778 c |

Converting the other way: degrees Celsius to degrees Fahrenheit
°F = °C × 9/5 + 32. So -8.333333 degrees Celsius is back to 17 degrees Fahrenheit; one degree Celsius is 33.8 degrees Fahrenheit. See the degrees Celsius to degrees Fahrenheit table.
Quick estimate in your head
Take away 30 and halve: (17 − 30) ÷ 2 = -6.5 °C, close to the exact -8.333333 °C for everyday temperatures.
Common mistakes
Multiplying without the offset is the usual slip: 0 °C is 32 °F, not 0 °F. Do the subtraction or addition in the right order, as in the formula above.
About the units
Degree Fahrenheit (f) and degree Celsius (c) are both units of temperature. Temperature scales have different zero points, so converting needs an offset as well as a multiplication. Results on this page are rounded for display; the conversion itself uses the exact definitions.
Temperature conversions come up in weather forecasts, cooking and oven settings, body temperature and science classes.

Questions
How many degrees Celsius are in 17 degrees Fahrenheit?
-8.333333 degrees Celsius.
What is the formula to convert degrees Fahrenheit to degrees Celsius?
°C = (°F − 32) × 5/9
How many degrees Celsius are in one degree Fahrenheit?
One degree Fahrenheit is -17.222222 degrees Celsius, but temperature scales have different zero points, so you cannot simply multiply by this number.
Is 17 f more than 17 c?
No. 17 degrees Fahrenheit is -8.333333 degrees Celsius, which is less than 17 degrees Celsius.
How do I convert degrees Fahrenheit to degrees Celsius in a spreadsheet?
Put the temperature in A1 and type =(A1-32)*5/9 in the next cell. Fill the formula down to convert a whole column.
