Why is Area?
Area is the measure of a two-dimensional surface, shape, or object. It is the space occupied by an object on a flat surface. Area is measured in different units such as square millimeters (mm2), square centimeters (cm2), square feet (ft2), square meters (m2), square yards (yd2), acres (ac), barns (b), etc.
How to Use
- The use of this area unit converter calculator is very simple.
- To convert the unit of any area value, you need to input the area and its unit in the respective field. Once you input the area along with its unit, the tool will display its converted values in various units.

How do You Convert from One Area Unit to Another?
Conversion of area values from one unit to another is a very simple process if you know the "conversion factor." There are two methods: using multiplication and division formulas to convert the area units. When converting from a smaller unit to a larger unit, the conversion factor is divided. On the other hand, when converting from a larger unit to a smaller unit, the conversion factor is multiplied by the area.
What is a Conversion Factor?
A conversion factor is a numerical value used to convert one unit into another. It is a ratio that tells how many of one unit are equal to another unit. For example, 1 square meter (sq.m) is equal to 10.7639 square feet (sq.ft). In this example, 10.7639 is the conversion factor, and it is used to convert the area unit from sq.m to sq.ft. You can use our tool above to find the conversion factors for other units.
Example :
1. How to convert 50 square feet into square yards?
Solution :
Now in the above example we have to convert the area value from smaller unit (square feet) to larger unit (square yard). So in this case we will divide the area value.
To convert the area value from square feet to square yards divide the area value of square feet by the conversion factor.
Conversion Factor = 1 square yard is equals to 9 square feet.
Square Yard = Area (square feet) / conversion factor
Square Yard = 50 / 9
Square Yard = 5.55555555556
Therefore, 50 ft2 is equal to 5.56 yd2.
Example :
2. How to convert 18 square meter into square inches?
Solution :
Now in the above example we have to convert the area value from larger unit (square meter) to smaller unit (square inch). So in this case we will multiply the area value.
To convert the area value from square meter to square inches multiply the area value of square meter by the conversion factor.
Conversion Factor = 1 square meter is equals to 1550 square inches.
Square Inch = Area (square meter) × conversion factor
Square Yard = 18 × 1550
Square Yard = 27900
Therefore, 18 m2 is equal to 27900 in2.
