I was taught, eh, by two Canadians, eh to double the Centigrade, eh, and add
it to 32 to get Fahrenheit, eh. Easy, eh? Not exact but close enough, eh?

Michael, eh

What two Canadians, eh? The Mackenzie Brothers, of course, eh?

No. It can be pretty far off. For example, for 100 C it would give 232 F
and would be too high by 20 F, giving 232 instead of 212. The correct
answer would be 200-20+32 = 212. It takes perhaps one second longer to do
the exact conversion.

Just to add what Jim left out, the -20 came from the 100+100 0
(-10%=-20) or 180+32 12. Another example: 0+0=0, 0-10%(0)=0, +32, and
15+15=30-10%(3) 7+32=59. So the formula is: ((Deg.C*2)-10%)+32=Deg.F
