Celsius. (C) = (5/9)(F-32) where C equals degrees of Celsius and F equals degrees of Fahrenheit.
88/9 C
At this temperature (-40), both scales have the same numeric value. -40 F = -40 C.In general, to convert between the two scales, use these formulae:C = (F - 32) x 5/9F = (5/9) C + 32
0 C = 32 F 100 C = 212 F 180 degrees F equals the measurement of 100 degrees C 9 degrees F therefore equals 5 degrees C -40 F is 72 degrees F below freezing -40 C is 40 degrees C below freezing Convert F to C 5 times -72 is -360 divided by 9 is -40 C convert C to F 9 times -40 is -360 divided by 5 is -40 F
F = C × 9/5 + 32 C = (F - 32) x 5/9
