Best practice

When comparing densities, ensure that the units of measurement are consistent. For example, compare densities in kg/m³ rather than mixing units.

Common error

Avoid using "lower density than" when you actually mean "lower mass than". Density is mass per unit volume, while mass is simply the amount of matter in an object.

Linguistic Context

The phrase "lower density than" functions as a comparative adjective phrase. It is used to compare the density of one substance or object to that of another, indicating that the first has a smaller mass per unit volume. Ludwig AI confirms its correct and frequent usage.
