Growing up in the United States, I am totally confused by most of the metric system measurements used in Japan. I understand 5Km, 10Km, and 42Km because they are running distances. Most everything else, especially temperature, I have no idea. See this little clip below and how easy it can be to convert temperature from Centigrade to Fahrenheit! Sugoi!
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

Hi Pamela,thats very clever,thankyou for sharing .
Great tip, Pamela!
I grew up with metric measurements, so no problems for me to understand what +10C feels like, but the formula works!
Good to know! We have trouble with the international communication of temperatures. :)
