      Each degree change in C is a 1.8 degree change in F. You're calculating what the temperature of 4 degrees C is in F, not what a change in 4 degrees C equates to in F.

        Isn't that the Kelvin/Rankine conversion since the two don't map linearly? (also I always thought Farenheit was based on the coefficient of heat expansion of Mercury, but the truth is far weirder. Who would use this scale?!)

      Zero celsius is 32 F. Each degree of Celsius is roughly 1.8 F.

      4 C is 39.2 F because 32+(4*1.8)=39.2.

      A 4 degree change in Celsius is 7.2 degrees of change in Fahrenheit. Use the tool you just used and look up 8 C. It should be 46.4 F, not 78.8 F.
