Unit Conversion
Area Converter – Convert Square Feet, Square Meters, Acres & Hectares
Use our free Area Converter to easily convert between square feet, square meters, acres, hectares, and other area units. Perfect for land measurement, real estate, and construction needs.
How Does Area Conversion Work?
Area measures the size of a two-dimensional surface and is expressed in square units. Converting between area units requires squaring the linear conversion factor — for example, since 1 foot = 0.3048 meters, 1 square foot = 0.3048² = 0.0929 square meters. This is why area conversions aren't as intuitive as length conversions.
This converter supports both metric units (mm², cm², m², km², hectares) and imperial units (in², ft², yd², acres, mi²). Simply enter a value, select your units, and get instant results with common conversions displayed automatically.

FAQ – Area Converter
What is an area converter?
An area converter is a tool that converts measurements between different units of area, such as square meters to square feet, acres to hectares, or square kilometers to square miles. It's essential for real estate, construction, land surveying, and any field that deals with surface measurements.
Why is area conversion different from length conversion?
Area is a two-dimensional measurement, so conversion factors must be squared. For example, 1 foot = 0.3048 meters, but 1 square foot = 0.3048 × 0.3048 = 0.0929 square meters. This is why 1 square meter equals 10.76 square feet (not 3.28, which is the linear conversion).
How many square feet are in an acre?
One acre equals exactly 43,560 square feet. An acre is roughly the size of a football field without the end zones (which is about 48,000 ft²). To convert acres to square feet, multiply by 43,560. To convert square feet to acres, divide by 43,560.
What is the difference between a hectare and an acre?
A hectare (ha) equals 10,000 square meters or about 2.471 acres. An acre equals about 4,047 square meters or 0.4047 hectares. Hectares are used in most countries worldwide, while acres are primarily used in the US, UK, and a few other countries.
How do I convert square meters to square feet?
Multiply the square meter value by 10.7639. For example, a 100 m² apartment equals 1,076.39 ft². To convert the other way (ft² to m²), multiply by 0.0929 or divide by 10.7639.
What area unit is used for real estate in different countries?
The US uses square feet for homes and acres for land. The UK uses a mix of square feet and square meters. Most of Europe, Asia, and Australia use square meters for homes and hectares for land. Japan uses tsubo (≈ 3.31 m²) alongside square meters. India uses square feet in many regions.
How big is a square kilometer compared to a square mile?
One square kilometer equals 0.3861 square miles, and one square mile equals 2.59 square kilometers. A square mile is about 2.6 times larger than a square kilometer. Manhattan is about 59 km² or 23 mi².
What is the smallest and largest area unit in this converter?
The smallest is square millimeters (mm²), used for precision engineering and electronics. The largest is square miles (mi²), used for geographic regions and countries. The range spans a factor of about 3.2 trillion between mm² and mi².
How do I calculate the area of a room?
Multiply the length by the width. For a rectangular room that is 12 feet × 15 feet, the area is 180 square feet (or about 16.7 m²). For irregular shapes, divide the space into rectangles, calculate each area separately, and add them together.
Can I use this converter for land and property measurements?
Yes. This converter handles all common land measurement units including acres, hectares, square feet, and square meters. It's suitable for residential property, agricultural land, commercial real estate, and construction planning. The common conversions feature shows multiple unit equivalents at once.
