What does one square decimeter represent?

One square decimeter is an area equal to a square with sides of one decimeter and equals 100 square centimeters or 0.01 square meters.

When should I use square millimeters instead of square decimeters?

Square millimeters are preferred for quantifying very small surface areas and detailed components, such as electrical conductor cross-sections or microfabricated parts.

Why might converting large square decimeter values be challenging?

Converting large square decimeter measurements to square millimeters can produce very large numbers, which may be unwieldy in documentation and require careful handling.
