How do you measure air density

WebIn simple terms, density is the mass of anything – including air – divided by the volume it occupies. In the metric system, which scientists use, we usually measure density in terms of kilograms per cubic meter. The air’s density depends on its temperature, its pressure and how much water vapor is in the air. WebFeb 5, 2024 · A material's density is defined as its mass per unit volume. Put another way, density is the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" an object has in a unit volume (cubic meter or cubic centimeter). Density is essentially a measurement of how tightly matter is crammed together.
