# Australia uses Celsius or Fahrenheit

## 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, countries in Europe degrees Celsius is used 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 the temperature in Kelvin).

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

To convert the temperature from degrees Fahrenheit to degrees Celsius, you have to subtract 32 from the reference number and add the result 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.
