Where each unit lives
Area units split cleanly by purpose. Homes are square metres in most of the world and square feet in the US and a handful of other markets. Land is hectares almost everywhere farming is discussed internationally, and acres in the US and UK. Countries and regions are square kilometres or square miles. The conversions between the two families are the ones people actually need, and they are all exact.
The useful anchors: 1 m² ≈ 10.76 ft², 1 hectare ≈ 2.47 acres, 1 km² ≈ 0.386 mi². For property, a 100 m² apartment is about 1,076 ft²; a quarter-acre plot is about 1,012 m², almost exactly a tenth of a hectare.
The square trap
The commonest area mistake is converting the lengths instead of the areas. A metre is 3.28 feet, so it is tempting to think a square metre is 3.28 square feet — but area scales with the square, so it is 3.28², which is 10.76. The same trap catches people going from centimetres to metres (÷100 for length, ÷10,000 for area) and from kilometres to miles. This converter applies the squared factor for you, and shows it.
Practical sizes for scale
A parking space is about 12 m². A tennis court is 261 m². A football pitch is about 0.7 hectares — 1.8 acres. A city block varies, but 2 hectares is typical. Helsinki is about 214 km²; Finland about 338,000 km². Having two or three of these in mind makes any figure you meet instantly checkable, which is the real point of a converter.

Questions people ask
How many square feet is a square metre?
One square metre is about 10.7639 square feet. For a quick estimate, multiply square metres by 10.75 — a 65 m² flat is roughly 700 ft².
What is the difference between an acre and a hectare?
A hectare is a metric unit: 10,000 m², a square of 100 m per side. An acre is imperial: 43,560 ft², about 4,047 m². One hectare is roughly 2.47 acres. Farmland in most of the world is quoted in hectares; the US and UK still commonly use acres.
How big is an acre, really?
About 90% of a football pitch, or a square of roughly 63.6 metres per side. It began as the area a team of oxen could plough in a day, which is why it is such an odd number in modern units.
Why can't I convert metres to square metres?
They measure different things — length versus area. A room 4 m by 5 m is 20 m², but that comes from multiplying two lengths, not converting one. This tool converts between areas only.
Which countries use square feet for homes?
The US, and informally the UK, Canada, India, Pakistan, Hong Kong and Singapore, among others. Most of Europe, including Finland, lists property in square metres. Cross-border property browsing is the single most common reason people need this conversion.
Are the conversions exact?
Yes. Imperial areas are the squares of the exactly defined 1959 lengths, so a square foot is exactly 0.09290304 m² and an acre is exactly 4,046.8564224 m². Only the displayed answer is rounded.
