It is hard to believe you when you say you can feel the difference between 71 and 72.
Kind of if i can feel the difference between 15,6 and 15,8 celsius.
No, it's the difference between 21.67 degC and 22.22 degC, a difference of 0.55 degC (the 5/9 conversion factor). I really can feel a 1 degF difference within certain ranges. In other ranges, of course not. For example, at 0 degF or -1 degF, the frozen tundra of Lambeau Field is still cold. But seeing those Vikings saunter off the field with their heads hanging warms me to my very soul.
The factor of 100 is pretty meaningless when it comes to scientific application of a temperature scale. It does help when working with distances, forces, pressures, etc.
Metric system proponents are all hypocrites anyway--they still use the old Babylonian sexagesimal (base 60) time unit (60 seconds in a minute, 60 minutes in an hour). Not to mention the Egyptian choice of 24 hours in a day. They similarly use the Greek sexagesimal metric for angles. Until they dump those units, I turn a deaf ear to their whining. The choice of units is meaningless if you're careful.
