the farhenheit scale is by definition inaccurate then Kelvin/Celsius. Why? because 0 and 100 degrees, the marker points are respectivly the coolest you can get water before it freezes and normal body-temp. Yes you can get water below 0°C before it starts to freeze if you are very carefull. The botom line is that body temp is clearly not a constant and they have been able to remain water as a liquid below what farhenheit ment to be 0 degrees. At my school using farhenheit is strictly forbidden hehe.
The inch is as accurate as the metre but its my opinion that 1/2, 3/0, 1/32 inch isnt that easy to visualize as just a number but that hase nothing to with inch or metre
anyway, i dont mean a thing with this , its just a thought
