Mass per unit of volume, calculated using density = mass ÷ volume.
Revise: Compound MeasuresDensity is not the same as mass: two objects made from the same uniform material can have different masses but the same density.
Use the units to sense-check a rearrangement. For example, leaves grams, so density multiplied by volume gives mass.
Use the context to check the direction of your answer: for a fixed force, a smaller area produces a greater pressure; for a fixed volume, greater mass produces greater density.
