Why Area Conversion Is Different From Length Conversion

Area uses squared units, so the conversion factor must also be squared.

For example:

but:

This is why converting square feet to square metres is not the same as simply multiplying by 0.3048.

Area Converter for Property in Australia

Property and land measurements in Australia commonly use square metres, hectares and square kilometres.

A residential block may be described as:

• 400 m²;
• 600 m²;
• 800 m²; or
• 1,000 m².

Larger rural properties may be described in hectares, while acres may still appear in older property information and international comparisons.

Area Converter for Construction

Area measurements are important when estimating materials for:

• Flooring;
• tiles;
• paint coverage;
• roofing;
• landscaping;
• decking; and
• other construction projects.

For project-specific estimates, you can also use the Flooring Calculator, Tile Calculator and Paint Calculator.

Area Converter for Land Size

Common land units include square metres, hectares and acres.

Useful reference values include:

• 1 hectare = 10,000 m²;
• 1 hectare ≈ 2.47105 acres;
• 1 acre ≈ 4,046.86 m²;
• 1 km² = 100 hectares; and
• 1 square mile ≈ 2.58999 km².

Area Converter for Room Size

Room areas are normally calculated by multiplying length by width.

For example, a room measuring 5 metres by 4 metres has an area of:

The converter can then convert 20 m² into square feet, square yards or other supported units.

Area Converter Assumptions

This converter uses standard international conversion relationships, including:

• 1 m² = 10,000 cm²;
• 1 m² = 1,000,000 mm²;
• 1 hectare = 10,000 m²;
• 1 km² = 1,000,000 m²;
• 1 ft² = 0.09290304 m²;
• 1 yd² = 0.83612736 m²;
• 1 acre = 4,046.8564224 m²; and
• 1 mi² = 2,589,988.110336 m².

Results may be rounded for display while calculations use the full factors defined in the converter.
