How many square feet are in a square metre?

1 square metre equals 10.7639 square feet, so to convert square metres to square feet you multiply by 10.764. Going the other way, a square foot is 0.092903 m², so multiply square feet by that figure (or divide by 10.764) to get square metres. This is the most-searched area conversion in the UK because property is advertised in both units — a 20 m² living room is about 215 sq ft, a 50 m² one-bed flat is roughly 538 sq ft, and a 90 m² house is close to 969 sq ft.

For a fast mental estimate, multiply square metres by 11 and round down slightly. That overshoots the true ×10.764 by about 2%, which is close enough to picture a room. The converter above does the exact arithmetic the instant you type, and the plain-English summary underneath restates the result in the everyday units people actually use.

How many square feet and square metres are in an acre?

1 acre equals exactly 43,560 square feet, 4,046.86 square metres, or 4,840 square yards. The acre has no tidy metric value because it is an old English land measure — historically the area a yoke of oxen could plough in a day, formalised as one chain (22 yards) by one furlong (220 yards). That 22 × 220 yard strip is 4,840 square yards, and there are exactly 640 acres in a square mile.

An acre is a little smaller than a full-size football pitch. A standard UK pitch of roughly 68 m × 105 m is 7,140 m², which works out to about 1.76 acres — so one acre is around 57% of a pitch, a useful mental picture when you are reading an estate agent's land listing. To convert the underlying lengths behind these areas — chains, furlongs, yards and metres — use the length converter.

How many acres are in a hectare?

1 hectare equals 2.47105 acres, because a hectare is 10,000 m² and an acre is 4,046.86 m². A hectare is a square 100 metres on each side, the standard unit for farmland and large sites across Europe and increasingly in UK planning. Multiply hectares by 2.471 to get acres, or acres by 0.404686 to get hectares. So a 5-hectare field is about 12.36 acres, and a 10-acre smallholding is roughly 4.05 hectares.

What is the difference between a hectare and a square kilometre?

1 square kilometre equals 100 hectares, or 1,000,000 m². Hectares suit fields and development plots; square kilometres suit towns, national parks and countries. As a worked example you can check against the tool, the City of London covers about 2.9 km² — enter 2.9 into the Square Kilometres field and the converter returns 290 hectares, 716.6 acres and 3,120,835 m². For the volumes those areas enclose once you add depth, see the volume converter.

What are the most common area conversions?

The table below covers the area conversions people look up most, from room sizes to farmland. Every figure is produced by the same converter above, so you can reproduce any row by typing the source value into its field and reading the rest.

Area scales with the square of length, which is why a room twice as long and twice as wide has four times the floor space, not twice. If you are estimating flooring, turf or paint, convert to the unit your supplier quotes first — many UK merchants price flooring per square metre but sell rooms measured in feet. For weights of materials that cover those areas, the mass converter handles kilograms, tonnes and imperial units.
