No account, no install, so you can convert areas for property, land, DIY and gardening on any device in seconds.
How to Convert Area Units Step by Step
- Enter the area. Type the area value you want to convert into the input field, such as a property size or a plot of land.
- Choose the starting unit. Select the unit your area is in, whether square metres, square feet, acres, hectares, or another area unit.
- Convert to other units. The tool converts your area into the other units, showing the equivalent values so you can see the area expressed however you need.
- Read the equivalents. See your area in the relevant units at once, letting you understand and compare it across metric and imperial units.
- Use the converted value. Apply the converted area to your property, land, DIY, or gardening task, working in whichever unit suits your purpose or region.
What the Area Units Are and Where They Are Used
Area, the measure of a two dimensional surface, is expressed in various units across the world and in different contexts. The metric system uses square metres, hectares and square kilometres, while imperial and US customary units include square feet, square yards, acres and square miles. Property, land and construction are common contexts for area, and since different regions and fields use different units, converting between them is a frequent need.
Area units, being based on squared length units, relate by factors that are the squares of the length conversion factors, which makes them larger and less intuitive than simple length conversions. Within metric, area units relate by powers of a hundred or ten thousand, reflecting the squaring, while imperial area units and cross system conversions involve non round squared factors that are hard to remember and easy to get wrong by hand.
Certain area units, like the acre and hectare, are specifically used for land and are not simple squares of everyday length units, adding to the complexity. An acre is a traditional unit of land area, and a hectare is the metric equivalent commonly used for land, each relating to the smaller area units by their own factors. Converting between these land units and others, or between systems, benefits from a converter that knows the factors.
Area conversion is useful for property and land, where sizes may be given in different units, for construction and DIY involving areas like flooring or painting, for gardening and landscaping, and more. Because area conversion factors are squared and often non round, and land units add complexity, doing conversions by hand is error prone. An area converter gives quick, accurate results for any area in any unit, useful across all these contexts.
Metric Versus Imperial Area Units
| System | Example units | Note |
|---|---|---|
| Metric | Square metres, hectares | Relate by squared factors |
| Imperial and US | Square feet, acres | Non round squared factors |
| Land units | Acre, hectare | Specific to land area |
| A converter | Handles all accurately | No need to memorise |

Frequently Asked Questions
How do I convert between area units?
Enter your area value and select its unit, whether square metres, square feet, acres, hectares or another, and the tool converts it into the other units, showing the equivalent values. This lets you express an area in whatever unit you need and compare it across metric and imperial units. Since area conversion factors are squared and often not round numbers, and land units like acres and hectares add complexity, the converter applies the correct factors exactly, giving accurate results without you needing to remember the fiddly squared and land unit conversion factors.
What are the main area units?
Area is expressed in various units. The metric system uses square metres, hectares and square kilometres, while imperial and US customary units include square feet, square yards, acres and square miles. Property, land and construction are common contexts. Some units, like the acre and hectare, are used specifically for land: an acre is a traditional land area unit, and a hectare is the metric equivalent commonly used for land. Because different regions and fields use different area units, and the units relate by squared and sometimes non round factors, an area converter is useful for converting between them accurately.
Why are area conversion factors squared?
Because area is a two dimensional measure, based on length squared, so its units are squared length units, like square metres or square feet. This means the conversion factors between area units are the squares of the corresponding length conversion factors. For example, the factor between two area units is the square of the factor between the related length units. This makes area conversion factors larger and less intuitive than length factors, and is a common source of error if you mistakenly use a length factor for area. Remembering that area factors are squared is important for understanding and correctly converting areas.
What is the difference between metric and imperial area units?
Metric area units include square metres, hectares and square kilometres, relating by squared factors such as powers of a hundred or ten thousand. Imperial and US customary units include square feet, square yards, acres and square miles, with non round squared factors between them. Some land units, the acre in imperial and the hectare in metric, are used specifically for land area. Converting between the metric and imperial area units involves non round squared factors that are hard to remember. Because different regions use different systems, converting between them is often needed, which an area converter handles accurately.
What are acres and hectares?
Acres and hectares are units of area used specifically for land. The acre is a traditional unit of land area, common in some countries for measuring plots and property, while the hectare is the metric unit commonly used for land, being the metric equivalent for such measurements. Neither is a simple square of an everyday length unit; each relates to the smaller area units by its own factor. So when dealing with land or property, sizes are often given in acres or hectares, and converting between these land units and others, or between the two, benefits from a converter that knows the specific factors involved.
Why is accurate area conversion important for DIY?
Because in construction and DIY, area determines how much material you need, such as flooring, paint, tiles, or turf, so an inaccurate area conversion can lead to buying too little or too much. If materials or plans use a different unit than you are working in, converting the area accurately ensures you calculate the right quantity. Relying on rough estimates rather than precise conversion risks getting the amount wrong, wasting money or effort or leaving you short. Using an area converter for accurate results, especially between metric and imperial with their squared factors, helps ensure you buy the correct amount of material for your project.
Should I convert areas to compare them?
Yes. To compare areas given in different units, you should convert them to the same unit first, since comparing across different units directly is confusing and error prone, especially with squared factors and land units involved. For example, comparing a property size in square metres with one in square feet without converting can mislead you about which is larger. By converting both to the same unit, you can compare them clearly. Standardising the unit before comparing ensures the comparison is valid and the result meaningful, whether comparing property sizes, land plots, or any areas given in different units.
Is the area converter free?
Yes, it is completely free with no account and no usage limit. You can convert as many areas between units as you like, as often as you like, at no cost. It runs entirely in your browser on any device, so there is nothing to download or install, and the equivalent areas in other units appear instantly whenever you enter a value and choose its unit, helping with property, land, construction, DIY, gardening and everyday area conversions.
