Conversion between Imperial Units of Measure of Area
Therefore, 1 ft = 144 in Likewise, 3 feet equals 1 yard. So, 9 ft = 1 yd .
Also, 5280 feet = 1 mile. Consequently, 27,878,400 ft = 1 mi .
Metric Units of Measure of Area
There is another system for measurement which is called metric system. The units of measuring length in the metric system are millimeter, centimeter, meter and kilometer. One can change one unit in the metric system to the others very easily. In the following table you could find the relation between metric units of measure length and area.
Metric Area Units
1 square centimeter (cm ) = 100 square millimeters (mm )
1 square decimeter (dm) = 100 square centimeter (cm )
1 square meter (m) = 100 square decimeter (dm )
To convert from square meters to square decimeter, square decimeters to square centimeters, and square centimeters to square millimeters, we use multiplication.
2 square meters = 2 x 100 = 200 square decimeters since 1 square meter = 100 square decimeter.
To convert from square decimeter to square meters, square centimeters to square decimeters, and square millimeters to square centimeters, we use division.
400 square centimeter = 400 ÷ 100 = 4 square decimeters because 100 square centimeter = 1 square decimeter.
