Land and floor area across metric and imperial

Convert hectares to acres, square feet to square metres or hectares to sotkas — the unit Eastern European land listings still use.

Area conversions turn up in two very different situations: comparing land plots and sizing a room. The units barely overlap, so a converter that only knows square metres is not much help when a listing is in acres.

This one includes the sotka — 100 m², the traditional plot unit across Russia and much of Eastern Europe. Six sotkas, the classic dacha allotment, is 600 m².

How to use

Enter an area.
Choose the units: square metres, square feet, square yards, square kilometres, acres, hectares or sotkas.
The result shows the converted area, the same area in square metres and what shape of plot it makes.

Square feet and square metres

A square foot is exactly 0.09290304 m², so a square metre is 10.764 square feet. A 1,000-square-foot flat is 92.9 m².

Acres, hectares and sotkas

An acre is 4,046.86 m² — 43,560 square feet — and a hectare is 10,000 m², or 2.471 acres. The sotka, used for plots in Russia and neighbouring countries, is 100 m².

What this calculator shows

The converted area across seven units including hectares, acres and sotkas
Square metres and square feet for interiors, larger units for land
Precision that holds up when comparing plots priced per unit

What to keep in mind

One hectare is exactly 10,000 m²; one acre is 4,046.86 m².
Land registry figures are often rounded before they reach a listing, so treat the source number as the weaker link.

FAQs

How many acres is one hectare?

2.471 acres. Going the other way, an acre is about 0.405 hectares — handy when farm sizes are quoted in the other system.

How many square feet are in an acre?

43,560 — which is 4,046.86 m². Half an acre is 2,023 m².

How many square feet is 100 m²?

1,076.4 square feet. One square metre is 10.764 square feet.

What exactly is a sotka?

One hundred square metres, literally 'a hundredth' of a hectare. Plots in Russia, Ukraine and neighbouring countries are still advertised in sotkas.

Where does the acre come from?

It was the area a team of oxen could plough in a day — one furlong long by one chain wide. The awkward 4,046.86 m² is a leftover of that.

Is a square foot the same as a foot square?

For one foot, yes: a square one foot on each side is one square foot. Beyond that the difference is expensive: a 'four foot square' is four feet on each side, which is sixteen square feet, not four.

Worked example

A dacha plot

Input: 6 sotkas → square metres

Output: 600 m²

Note: Also 0.06 hectares, or about 0.148 acres — a useful cross-check when comparing listings written in different conventions.
