Area Converter
Convert between square meters, acres, hectares, square feet, square miles, and more area units.
Each step along the axis is ten times the one before — the area units span 12 orders of magnitude, so a straight scale would bunch almost all of them at one end.
Instant insight
That is about 38.61% of a square mile
1,000,000 square metres — 2.59 km².
Anchors like this are the quickest way to catch an answer that is out by a factor of ten.
Area scales with the square of length
Doubling a room’s dimensions quadruples its floor area — and one square metre is 10,000 cm², not 100.
When a converted area looks wrong by a round factor, a length conversion has probably been applied once instead of twice.
Check the direction of the conversion
Going from square_kilometer to square_meter, the number should get bigger if the new unit is smaller, and smaller if it is bigger.
If it moved the wrong way, the factor has been applied upside down — the most common conversion error there is.

Everyday Uses
Property listings
One listing says 1,200 sq ft, another 120 m² — convert to compare apartments honestly (they're almost the same size).
Lawn and garden
Fertilizer coverage is "per 1,000 sq ft" but you measured in square meters — convert so you buy one bag, not three.
Paint coverage
A liter covers 10 m²; your walls are measured in square feet. Convert the area to get the right number of cans.
Land talk
Acres, hectares, square meters — translate land sizes when comparing plots, reading news, or handling inherited property.
Buying turf or seed
Lawn products are sold per square metre or square foot depending on supplier. Convert before ordering to avoid a shortfall.
Comparing property listings
Listings quote square feet in some countries and square metres in others — convert to compare two homes honestly.
Frequently Asked Questions
How many square feet are in an acre, and how big is an acre visually?
1 acre = 43,560 square feet = 4,046.86 m². As a visual reference: 1 acre is approximately 90% of an American football field (field + end zones = 1.32 acres), or a square roughly 208 × 208 feet (63 × 63 metres). Historically, an acre was the amount of land a man could plow in one day with a yoke of oxen. A standard city block in the US is typically about 2–5 acres.
What is the difference between an acre and a hectare?
1 hectare = 10,000 m² = 2.471 acres. 1 acre = 0.4047 hectares. Hectares are used in most of the world (metric system) for land measurement; acres are used in the US, UK, and some Commonwealth countries. Quick reference: 5 acres ≈ 2 hectares; 100 acres ≈ 40.5 hectares; 1 square kilometre = 100 hectares = 247.1 acres.
How do you convert square meters to square feet and vice versa?
1 m² = 10.7639 sq ft. To convert m² to ft², multiply by 10.764. To convert ft² to m², multiply by 0.0929. Example: a 30 m² studio apartment = 30 × 10.764 = 323 sq ft. A 2,000 sq ft American house = 2,000 × 0.0929 = 185.8 m². Quick approximation: multiply m² by 10.75 (or divide sq ft by 10.75 for m²).
How many square meters are in a square kilometer, and how does it compare to square miles?
1 km² = 1,000,000 m² (1 million square metres). 1 square mile = 2.59 km² = 640 acres. 1 km² = 0.386 square miles = 247.1 acres. Country size references: Luxembourg ≈ 2,586 km²; England ≈ 130,279 km²; France ≈ 551,695 km²; USA ≈ 9,833,517 km²; Russia ≈ 17,098,242 km².
What area units are used in different countries for real estate?
Real estate area conventions vary widely: USA/Canada: square feet (sq ft) for homes; acres for land. UK: square feet for homes; acres and hectares for land. Europe: square metres (m²). India: square feet, but also "square yards," "cents" (1/100 acre), and "guntha." Japan: tsubo (1 tsubo = 3.306 m² ≈ 35.6 sq ft). Middle East: square metres. Australia/NZ: square metres; hectares for rural land. When comparing international property listings, always check which unit is being used.
