For those used to Fahreneit degrees and not knowing what Celsius is :) or the reverse, these are some basic grades, side by side:

 

FAHRENEIT TO CELSIUS

32F = 0C

40F = 4C

50F = 10C

60F = 16C

70F = 21C

80F = 27C

90F = 32C

100F = 38C

110F = 43C

 

CELSIUS TO FAHRENEIT

10C = 50F

15C = 59F

20C = 68F

25C = 77F

30C = 86F

35C = 95F

40C = 104F

45C = 113F
