Intersesting correspodences are 16C=61F....28C=82F.

....give or take a bit.   16^oC = 60.8^oF
                                    28^oC = 82.4^oF

The problem with the Celsius scale is that 1 degree is such a large change in temperature.

From experience, 1 degree Fahrenheit appears to be the "sensible" change in temperature. If I think "it's getting a bit warm/cold in here" then the temperature has changed by about 1^oF (assuming that I'm not in a draught). Hence the unusual number of 180 degrees between freezing and boiling compared to Celsius's convenient 100 degrees.
