Those of us in America measure temperature in degrees Fahrenheit. The rest of the world measures temperature in degrees Celsius.
Occasionally you may want to know the temperature in your familiar Fahrenheit, but only know the temperature in Celsius.
There is an easy way to convert them, approximately: times two and add thirty two
For example: 10 degrees C x2+32 is 52 degrees F
This is not exactly correct, but it is reasonably accurate.
According to this website 10 degrees C is actually 50 degrees F.
Times two plus thirty two is a lot easier than doing the real math.
How often do you need the exact temperature anyway?
An easy to remember formula is -40 times (9 or 5) divided by (5 or 9) + 40.
ReplyDeleteCelsius and Fahrenheit are equal at negative 40 degrees. If you are going to F multiply by 9 and divide by 5.
If you are going to Celsius, multiple by 5 and divide by 9.
Your formula definitely works better without the math.
