Frequently Asked Questions
Why does Australia use metric instead of imperial?
Australia converted to metric in the 1970s for international trade alignment, scientific standardisation, and to modernise alongside most other countries. The UK (Australia's historical measurement reference) subsequently moved to metric for most purposes. Today, the US is the only major economy still primarily using imperial for everyday measurements.
Quick Celsius to Fahrenheit mental calculation?
Approximate formula: (°C × 2) + 30 ≈ °F. Example: 25°C ≈ (25×2)+30 = 80°F (exact: 77°F). For cold temperatures: 10°C ≈ 50°F (exact: 50°F — this one's exact!). For Australian everyday use, the approximation is close enough.
Are UK gallons and US gallons the same?
No — they're significantly different volumes. 1 UK (imperial) gallon = 4.546 litres. 1 US gallon = 3.785 litres (about 20% smaller). Australia never officially used gallons — all fuel has been sold in litres since metrication. When old Australian cars quote 'mpg' fuel economy, they typically mean UK mpg.
What is a 'stone' in Australian weight measurement?
A stone is 14 pounds or 6.35 kilograms — an old British imperial unit. It was used in Australia before metrication for body weight. Some older Australians still refer to their weight in stone informally, but medical, sports and official contexts all use kilograms.
