# How many decimeters are in one kilometer?

1 km = 1000 m

1 dm = 0.1 m

So, 10,000 dm = 1 km.

### Here's a calculation showing units:

(1000 m/km) / (0.1 m/dm) = (1000 m/km) * (1 dm / 0.1 m) = 1000 dm / 0.1 km = 10,000 dm/km.

### How many liters in cubic kilometer?

A liter is a cube exactly one tenth of a meter (1 decimeter) on a side. There are ten decimeters in a meter and so ten thousand of decimeters in a kilometer (1000 meters) There are exactly: 10 000 * 10 000 * 10 000 = 1 000 000 000 000 liters in a cubic kilometer (1012) (in the English language there are conflicting names for this number so I won't write the name in…
