About this calculator
This converter changes an area measurement from one unit into another, spanning small metric units like square metres, land units like acres and hectares, and large units like square miles. It is useful for real estate listings, land surveying, gardening, and comparing property sizes described in different countries' preferred units.
How it works in plain English
Each area unit is linked to a single base unit, the square metre, through a fixed factor, and the tool converts by multiplying your entered value by the factor for the starting unit, then dividing by the factor for the target unit. Because area is a two-dimensional quantity, its factors are often the square of the corresponding length factor, though land units like acres and hectares are defined with their own historical or round-number values rather than as simple squares.
Square metres, square kilometres, and hectares belong to the metric system and scale in round numbers, with one hectare equal to ten thousand square metres. Square feet, square yards, acres, and square miles are commonly used in the United States and some other countries, with the acre originating from the amount of land a team of oxen could plow in a day, later standardized to an exact figure.
To convert, choose your starting and target units, then type a value; the result recalculates instantly as you type. The tool also displays a table showing that same area expressed in every supported unit at once, useful for comparing a plot of land in acres, hectares, and square metres simultaneously, and you can adjust the displayed decimal precision to suit your needs.
The formula
- value_in_m2 = value x factor_from
- result = value_in_m2 / factor_to
- 1 acre = 4046.8564224 m², 1 ha = 10000 m², 1 ft² = 0.09290304 m², 1 mi² = 2589988.110336 m²
Worked example
Suppose you want to convert 3 acres into hectares. The tool first multiplies 3 by the acre factor, 4046.8564224, giving 12140.5692672 square metres.
It then divides that figure by the hectare factor, 10000, giving 1.21405692672 hectares. If you wanted square feet instead, the same square metre value would be divided by the square foot factor, 0.09290304, giving roughly 130,680 square feet. Every result traces back to the same square metre figure, so comparing several units for the same plot of land, whether described in acres, hectares, or square feet, always stays internally consistent and free of accumulated rounding error.

Frequently asked questions
How big is an acre in more familiar terms?
An acre equals 4046.8564224 square metres, or about 0.405 hectares. It is roughly the size of a standard American football field without the end zones, and it remains a common unit for describing land and farm sizes in several countries even where metric units are otherwise standard.
What is the difference between a hectare and an acre?
A hectare equals exactly 10,000 square metres, while an acre equals about 4046.86 square metres. A hectare is therefore larger, roughly 2.47 acres. Hectares are used almost everywhere for land measurement, while acres remain common mainly in the United States and a handful of other countries.
Why isn't the acre a round number of square metres?
The acre originated from old English land measurement based on plowing, long before the metric system existed, so its metric equivalent was calculated afterward rather than designed to be round. Once international length units were standardized, the acre's exact square metre value followed automatically from those length definitions.
Can I convert square miles into hectares?
Yes. Square miles convert through the shared square metre base value just like every other area unit, so entering a square mile figure and choosing hectares as the target gives an accurate figure, useful for comparing large regions like parks, districts, or agricultural zones.
How do I compare a land size in several units at once?
After entering a value and selecting a starting unit, the results table shows that same area converted into every supported unit simultaneously, letting you view acres, hectares, square metres, and square feet together without recalculating each one separately.
