Frequently Asked Questions

Does Australia use metric or imperial?
Australia officially adopted the metric system in 1970. All road signs, weather reports, and official measurements use metric (kilometres, kilograms, Celsius). However, some imperial units persist in everyday language — many Australians still refer to height in feet/inches, weight in stone, and screen sizes in inches.
How do I convert Celsius to Fahrenheit?
Multiply the Celsius temperature by 9/5 (or 1.8) and add 32. For example: 25°C × 1.8 + 32 = 77°F. Quick reference: 0°C = 32°F (freezing), 20°C = 68°F (comfortable), 30°C = 86°F (warm), 40°C = 104°F (very hot).

What is Unit Converter?

A unit converter converts measurements between metric and imperial systems. Australia officially uses the metric system, but imperial units are still common in everyday life, international trade, and when reading American or British content.

How this calculator works

Select a category (length, weight, temperature, area, volume, or speed) and the available units update accordingly. Enter a value in any unit and the converter instantly shows the equivalent in all other units of that category. The swap button reverses the conversion direction. Australian-relevant conversions include kilometres to miles, kilograms to pounds/stone, Celsius to Fahrenheit, hectares to acres, and litres to gallons. The 'all units' list shows every conversion at once, making it easy to find the one you need.
