Decimal metric system: length, mass, capacity, surface and volume

Convert the following quantities into the sizes indicated:

The original unit (the dl) is less than what you want to get (the decaliter). Therefore, it will be divided by $10$ the same number of times as it has rows to climb. In this case there are two, so we divide by $100$: $$16.000:100=160 \ \mbox{dal}$$
The original unit (the decameter cubic) is greater than what we want to get (cubic meter). So you have to multiply the original amount by $1.000$ the same number of times as there are rows it must climb down. As you only need to move down one row, we have: $$0,0378\cdot 1000= 37,8\mbox{m}^3$$
