Click on the following link if you want to convert square centimeters to square decimeters – cm² to dm²
History
Both the square decimeter (dm²) and the square centimeter (cm²) belong to the metric system introduced in France in the 1790s to standardize measurements worldwide.
A decimeter is one-tenth of a meter, while a centimeter is one-hundredth. Because we are converting areas, the ratio must be squared:
(10 × 10) = 100
So, 1 dm² = 100 cm².
Common Usage
- Square decimeters (dm²) are often used for medium-sized surfaces, such as books, posters, or furniture panels.
- Square centimeters (cm²) are used for smaller areas, like packaging labels, phone screens, or drawings.
For example, a sheet of paper that measures 2 dm² has an area of 200 cm².
Conversion Formula
The relationship between these units is very simple:
cm² = dm² × 100
Example:
Convert 4 dm² to square centimeters.
4 × 100 = 400 cm²
So, 4 square decimeters equal 400 square centimeters.
