Square Kilometer (km²)

The square kilometer (km²) measures large territories and urban districts.

Origin
The area of a square with 1 km sides, a decimal multiple of the square meter.
Where it is used
Used for regional planning, catchment analysis and mapping.
Relation to SI
1 km² = 1,000,000 m² = 100 ha.

Square Foot (ft²)

The square foot (ft²) is the standard floor area unit in US and partly UK real estate and construction.

Origin
The area of a square with 1 ft sides, based on the 0.3048 m international foot.
Where it is used
Used for leasable area, rents, cost per area and finish quantities.
Relation to SI
1 ft² = 0.09290304 m² exactly, so 1 m² is about 10.764 ft².

Frequently asked questions

How many square feet are in one square kilometer?

1 km² equals 10,763,910 ft².

How do I convert square kilometers to square feet?

Multiply the value by 10,763,910. For example, 10 km² equals 107,639,100 ft².

How do I convert back from square feet to square kilometers?

1 ft² equals 9.290304 × 10⁻⁸ km². The converter above works in both directions, so you can type into either field.

When should I use hectares instead of acres?

Hectares are the metric standard for site and land areas in most planning systems, while acres remain common in US and UK land records. Use whichever the local authority requires and quote the other in brackets.

How do I convert a length ratio into an area ratio?

Square the length factor. Because 1 ft = 0.3048 m, one square foot is 0.3048², which is 0.09290304 m².
