To convert a temperature from Fahrenheit to Celsius, you can use the formula C =5(F −32),whereC is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit. How would I use formula to work out the Celsius equivalent of −10◦F.

Many thanks

You have the formula wrong

C = (5/9)(F-32)

check

when F = 32, C = 0 freezing point- right

when F = 212, C=100 boiling point - right

so

put in -10 for F

C = (5/9)(-42)

I think you can do that.
