Convert between square meters, hectares, acres, square feet and 13 area units at once. Live results, adjustable decimals and one-click copy.

Area Converter for Metric and Imperial Units

The Area Converter changes a value from one area unit into every other unit at once, so you can move between square meters, hectares, acres, square feet, and more without doing the math by hand. Type a number, pick a unit, and read the converted results instantly.

It is built for anyone who compares land or surface sizes across systems: real estate professionals, farmers and landowners, architects and builders, students, and travelers sizing up property abroad. The tool covers 13 area units split into Metric and Imperial groups, with a side-by-side converter card for a single from-to conversion and a full results list for everything else.

Private by design: every conversion runs in your browser. Nothing you type is uploaded, stored on a server, or tracked.

How to Use the Area Converter

1

Enter a value

Type your number into the "from" field of the converter card. Decimals are supported, and you can use a comma or a period as the decimal mark.

2

Choose your units

Open the unit dropdown and start typing to search for a unit by name or symbol, like "hec" for Hectare or "ac" for Acre. Set the "from" unit, and pick a "to" unit for the side-by-side result. Use the swap button to reverse the two.

3

Read every conversion

Below the card, the results list shows your value in all enabled units, grouped by Metric and Imperial. The results update live as you type.

4

Adjust and copy

Use the Decimals selector to set precision, open Customize Units to show only what you need, then copy a single row or use Copy All Results to grab everything at once.

Frequently Asked Questions

How do I convert square meters to square feet?

Enter your value with Square Meter (m²) as the source unit, then read the Square Foot (ft²) result. For reference, 1 square meter equals about 10.764 square feet.

How many square feet are in an acre?

One acre equals 43,560 square feet, or about 4,047 square meters. Set the source unit to Acre (ac), enter 1, and the Square Foot and Square Meter rows show the exact figures.

How many square meters are in a hectare?

A hectare (ha) equals exactly 10,000 square meters. It is the standard land measurement unit in most countries, and one hectare is about 2.47 acres.

How do I convert acres to hectares?

Choose Acre (ac) as the source unit and read the Hectare (ha) row. One acre is about 0.405 hectares, so to go the other way, one hectare is roughly 2.47 acres.

What is the difference between a hectare and an acre?

A hectare equals 10,000 square meters and is the metric land unit used in most of the world. An acre equals about 4,047 square meters and is common in the United States and United Kingdom. One hectare is roughly 2.47 acres.

What is the formula to convert area units?

Every unit is defined relative to the square meter (the base unit). To convert, multiply your value by the source unit's square-meter factor, then divide by the target unit's factor. This tool does that automatically, so you only enter a number and pick units.

What are an Are and a Rood?

An Are (a) is a metric unit equal to 100 square meters, so 100 ares make a hectare. A Rood (ro) is a historical English unit equal to one quarter of an acre, about 1,012 square meters. Both are uncommon today but may appear in older documents.

How accurate are the conversions?

Conversions use standard conversion factors and are accurate to many decimal places. Use the Decimals selector to show up to 8 decimal places, or Auto for a balanced display.

Can I use this tool to calculate area from length and width?

This tool converts between area units rather than calculating area from dimensions. To find area first, multiply length by width for a rectangle, or use π × radius² for a circle, then convert the result here.
