# Why does Canada use Celsius

## Conversion from degrees Fahrenheit to degrees Celsius and vice versa

Fahrenheit and Celsius degrees are the most common degrees for temperature measurement. Degrees Fahrenheit is only applicable in the United States everywhere. In such countries as Australia, Canada, New Zealand, European countries they use degrees Celsius but sometimes the older generation measure the temperature in degrees Fahrenheit. In fact, all other countries only use degrees Celsius (except for scientific tasks where it is common to measure temperature in Kelvin).

But it is the custom in most countries, for your convenience, to measure the temperature in Celsius. This is because the points of change in the state of the water are as follows: at 0 degrees Celsius the water freezes over, at 100 degrees Celsius the water begins to boil. In this way the temperature measuring scale according to Celsius appeared.

To convert the temperature from degrees Fahrenheit to degrees Celsius, you need to subtract 32 from the reference number and add the result with 5/9 to multiply.
To convert the temperature from degrees Celsius to degrees Fahrenheit, you need the reference number with 9/5 multiply and add 32

The following technique can be used to quickly approximate the size of degrees Fahrenheit to degrees Celsius in your head: subtract 32 from the reference number, then divide by two and add one tenth of this size.

For example, 72 ° F is approximately equal to (72 - 32) / 2 = 20 plus 1/10 of 20, i.e. 22 ° C.
