Frequently Asked Questions

Common questions about Australian land measurement units answered by property experts.

What is the standard land measurement unit in Australia?
The square metre (m²) is the standard and official land measurement unit in Australia for property transactions, land titles, and construction. Australia officially uses the metric system, making square metres the primary unit for land area measurement.
A "house square" or "builder's square" is a uniquely Australian measurement equal to 100 square feet (approximately 9.29 square metres). It's commonly used in the building industry to describe floor areas of houses and buildings. For example, a 25-square house has approximately 232 square metres of floor area.
Yes, acres are still commonly used in Australia, particularly for rural and agricultural land. While Australia officially uses the metric system, acres remain in use due to historical reasons and are often used alongside hectares for larger land parcels like farms, stations, and rural properties.
To convert square metres to hectares, divide the number of square metres by 10,000. For example, 5,000 m² equals 0.5 hectares. One hectare is exactly 10,000 square metres. You can use the converter above for instant calculations between any Australian land units.
Australian property certificates (titles) primarily use square metres for land area. However, you may occasionally find older titles that reference acres, perches, or roods. Since the 1970s metrication, all new land titles and subdivisions have used metric measurements.
Square metres are the official metric unit used for land and property area in Australia. Square feet are sometimes used informally, especially for interior spaces. One square metre equals approximately 10.764 square feet. Property listings typically show both measurements for clarity.
Multiply the length by width (in metres) to get area in square metres, then divide by 10,000 to convert to hectares. For example, a rectangular block measuring 200m × 150m = 30,000 m² = 3 hectares. For irregular shapes, you may need to divide into regular sections and sum the areas.
