Unit Converter: how it works
Convert between metric and imperial units for length, mass, volume, area, speed and temperature. Australia uses metric, but you'll still meet feet, pounds and Fahrenheit in recipes, specs and overseas listings.
Australian real estate sometimes quotes house size in squares: one square is 100 square feet, or about 9.29 m².

°F = °C × 9/5 + 32. So 25 °C is 77 °F.
