Decimeters to kilometers

This free conversion calculator will convert decimeters to kilometers, i.e. dm to km. Correct conversion between different measurement scales.

The formula is $$$L_{\text{km}} = \frac{1}{10000} L_{\text{dm}}$$$, where $$$L_{\text{dm}} = 15$$$.

Therefore, $$$L_{\text{km}} = \frac{3}{2000}$$$.

Answer: $$$15 \text{dm} = \frac{3}{2000} \text{km} = 0.0015 \text{km}$$$.
