# What are the units of density for a liquid usually expressed as?

May 14, 2018

Are not the units of density, $\rho$, $\text{mass per unit volume...}$?
And so for chemists, typically we would express density as $g \cdot m {L}^{-} 1$, or $g \cdot c {m}^{-} 3$...where $1 \cdot c {m}^{3} \equiv 1 \times {\left({10}^{-} 2 \cdot m\right)}^{3}$ $1 \times {10}^{-} 6 \cdot {m}^{3}$..i.e. there are $1000 \cdot L$ in a ${m}^{3}$, and $1000 \cdot c {m}^{3} \cdot {L}^{-} 1$...
