A Little Trick for Converting Centigrade to Fahrenheit

Jump to last reply

If you're like me, you still can't help wanting those temps in Fahrenheit. But if mentally trying F = 9/5C + 32 doesn’t work for you, here’s a tip on quickly making the conversion in your head when in Africa (or most places in the world).

Some years ago I was visiting a colleague in Canada, who saw me staring at a temperature sign given in Centigrade. He must have figured I was trying to use the standard formula (F = 9/5C + 32) to work out the Fahrenheit value, so he gave me this tip: double the Centigrade temp, subtract the first digit of the result from the result and add 32. It works pretty well; you’re usually right on but you’ll never be more than 1 degree Fahrenheit off.

For example, 23 C equals 74 F.
23 C x 2 = 46;
46 – 4 = 42;
42 + 32 = 74 F

or (an actual temp during a Christmas visit in Kruger)

42 C x 2 = 84;
84 - 8 = 76;
76 + 32 = 108 F
