How to convert convert area measurements between 10 common units.
Theory:There are many different units of area, such as 'square centimetres', 'hectares', 'square feet' and 'acres'. To change the units of a quantity, it is multiplied or divided by some constant value, called a conversion factor. This table lists ten different area units, and values that will help you change units of area measurements:
This is how you can change the units of an area measurement: If possible, find an equation in the table that contains both the units you are converting from, and the units you are converting to. Example 1  Convert 25 yd² to m²
The number: '0.8361' is the conversion factor. To convert the units on the left to the
units on the right, you multiply by the conversion factor. So to change 25 yd² to square metres, multiply by 0.8361 ...
Example 2  Convert 3.5 hectares to km²
The number: '100' is the conversion factor. To convert the units on the left to the
units on the right, you multiply by the conversion factor. So to change 3.5 ha to km², divide by 100 ...
Example 3  Convert 2.5 square miles to hectares
To convert the units on the left to the units on the right, you multiply by the conversion factor.
To convert the units on the left to the units on the right, you multiply by the conversion factor.
