This is a tricky one... And I am answering it for the volume of a liquid... the answer is liter (or litre)

#### Explanation:

The reason this is tricky (and someone is will raise this on here) is the litre was originally incorrectly defined. It was supposed to be 1000 $c {m}^{3}$ but was slightly off (I think it was something like 1000.0028 $c {m}^{3}$, but don't quote me on that as I can't remember the exact figure). So, for awhile volume was defined as ${\mathrm{dm}}^{3}$ which is exactly 1,000 $c {m}^{3}$ (it's a 10 cm by 10 cm by 10 cm cube). However, now it is back as the liter or litre.

Below is a handy chart of SU Units:
