Area Converter: Complete Guide with Formulas and Real-World Applications
What is Area Conversion?
Area conversion is the process of changing a measurement from one unit of area to another. This is essential in many fields including real estate, agriculture, construction, and science. Common systems include metric units (square meters, hectares) and imperial units (square feet, acres).
The conversion is based on fixed relationships between units. For example, 1 square meter equals 10,000 square centimeters, and 1 acre equals 43,560 square feet according to the international standard.
Area Conversion Formulas
The general formula for area conversion is:
Converted Value = (Input Value × Target Factor) / Source Factor
Using square meters as the base unit, the conversion from unit A to unit B is:
- Step 1: Convert input value to square meters: Value × FactorA
- Step 2: Convert square meters to target unit: (Step 1 result) / FactorB
How to Convert Area Units
To convert between area units:
- Identify the units: Determine the original unit (e.g., acres) and the target unit (e.g., square meters)
- Find conversion factors: Look up how many base units (square meters) each unit represents
- Apply the formula: Multiply by the source factor and divide by the target factor
- Calculate: Perform the arithmetic to get the converted value
Our calculator automates this process, providing accurate conversions instantly.

Area Conversion Tips
Here are some helpful tips for area conversions:
- Remember that 1 acre equals 4,046.86 square meters or 43,560 square feet
- Remember that 1 hectare equals 10,000 square meters or about 2.47 acres
- For quick estimates: square feet ÷ 10.764 ≈ square meters
- For quick estimates: square meters × 10.764 ≈ square feet
- A hectare is about the size of a rugby field or 100 ares
- An acre is about the size of a football field without the end zones

FAQs
What is the difference between area and length?
Length is a one-dimensional measurement (distance), while area is a two-dimensional measurement (length × width). Area describes the size of a surface, while length describes the size of a line.
How many square feet are in an acre?
There are exactly 43,560 square feet in one acre. This conversion factor is based on the international acre definition.
How do I convert acres to hectares?
To convert acres to hectares, multiply the area in acres by 0.404686. For example, 10 acres × 0.404686 = 4.04686 hectares.
What is the difference between a hectare and an acre?
A hectare is 10,000 square meters, while an acre is 4,046.86 square meters. Therefore, 1 hectare equals approximately 2.47 acres, or 1 acre equals approximately 0.405 hectares.
How many square meters are in a hectare?
There are exactly 10,000 square meters in a hectare. The prefix "hecto-" means 100 in the metric system, so a hectare is 100 ares, and 1 are is 100 square meters.
