# What are the typical units for volume, pressure and temperature?

For chemists, volume is measured in $\text{litres}$; pressure in $\text{atmospheres}$; and temperature in $\text{degrees Kelvin}$.
Volume and pressure use non SI units here, but these are hallowed by usage, and I doubt that chemists will abandon them without protest. Sometimes, INSTEAD of litres we see $\text{cubic decimetres}$, i.e. ${\mathrm{dm}}^{- 3}$, which is equal to ${\left({10}^{-} 1 \cdot m\right)}^{3}$ $=$ ${10}^{-} 3 \cdot {m}^{3}$ $=$ $1 \cdot L$ because there are $1000 \cdot L$ in a cubic metre volume.
For pressure, we should use $\text{pascals}$, but I don't think the $\text{atmosphere}$ is going to fall out of use too quickly. Why not? Because $\text{atmospheres}$ are (i) intuitive, and (ii) handy to measure with a mercury column.
