I consider myself pretty conversant in metric units.
But Celsius temperatures are trickier.
Instead of memorizing a one-step formula, try these three trickstwo of which require zero math.
(It’s 32 degrees Fahrenheit.)
100 degrees Celsius is the boiling point of water.
(It’s 212 degrees Fahrenheit.)
Zero degrees Fahrenheit, as a weather forecast, is bitterly cold.
(-18 degrees Celsius.)
100 degrees Fahrenheit, as a weather forecast, is sweltering hot.
(38 degrees Celsius.)
For temperature, though, you should probably account for the different unitsandthe different baseline.
So it’s a two-step process: you gotta multiplyandadd (or subtract and divide).
I used the decimals here because we all carry calculators now.
In any case, there are easier ways to do this in your head than memorizing formulas!
I’ll give you three options, in order from least math to most.
Memorize this poem to convert Celsius to Fahrenheit without any math
Still too much math?
If the forecast is around 10 degrees, you need a light jacket.
If it’s over 30, that’s beach weather.
Heres the trick: You reverse the digits of these specific numbers.
04 degrees Celsius is 40 degrees Fahrenheit (chilly!)
The Celsius degrees are always the smaller number of the pair, so 61 Fahrenheit is 16 Celsius.
And by the way: The numbers are all 12 apart.
(4 + 12 = 16, 16 + 12 = 28, etc.)
The only weird one here is 40, but now that youve read it, you get the idea.
Four degrees Celsius is 40 Fahrenheit, and 40 Celsius is 104 Fahrenheit.
Its tank top and shorts weather.
And to do it the other way around: 72 Fahrenheit is 40/2, which is 20 Celsius.
