Quickly convert Fahrenheit to Celsius (Centigrade) temperature

Updated on November 19, 2012

Fahrenheit to Celsius vice versa

It is getting colder and, are you traveling outside US? Do you want to understand temperature measure system in other countries like Asia or Eurpoe? They are talking with different numbers among people and media. Do you want to quickly convert Fahrenheit to Celsius or vice versa?

Here is a quick way but very close.

Please rember the magic number 32. You need to take 32 when either adding or subtracting. Also please notice the factor, either half or double.

Now, let's try a couple of examples.

First, Convert from Farenheit to Celsius. The number for Celsius will go down.

--- Subtract 32 from Farenhiet, and take a half of it. ---

Since you are already going down, take a little bit of hike (by 10% of what you got). If you don't want to adjust by 10%, the result will be still good enough.

Let's say the current temperature is 50 in Fahrenheit degrees.

1. Subtracting 32 from 50 would give 18.

2. Then the half of 18 would be 9. Then take of 10% of 9 would be 0.9.

3. Add 0.9 to 9 and you will get 9.9, which is almost 10 Centigrade. People using Centigrade know that 10 is mild spring weather. 9 degree without adjustment is still good.

Secondly, Convert Celsius to Farenheit. The number for Celsius will go up.

Since you are going up and up, you need to cut the result a little down. I guess this would be a real example that most of American will face it.

--- Double the Celsius, and add 32 to it. Then, take a little cut down. ---

Let's say we have 5 degrees in Centigrade.

First, double the number and we have 10. Adding 32 to 10 is 42, which is still good.

(In fact, the follwoing would be more accurate.

First double the number and we have 10. 10% of 10 is 1.

Subtracting 1 from 10 will give 9.

If we add 32 to 9, we will have 41 which would be a chilly weather. )

In either conversion, the result are still good and easy to convert even without a minor adjustment. I hope this helps a lot of people to understand the different numbers. Thanks.
