Square decimeter to square kilometers Conversion

1 square decimeter (dm²) is equal to 0.00000001 square kilometers (km²).

1 dm² = 0.00000001 km²

1 km² = 100000000 dm²

Formula

To convert a area from square decimeter (dm²) to square kilometers (km²), divide the area in square decimeter by 100000000

a_(km²) = a_(dm²) / 100000000

Examples:

Convert 100 square decimeter to square kilometers:

a_(km²) = 100dm² / 100000000 = 0.000001 km²
