Q:

# What is the unit of density?

A:

Density it the relationship between the volume and mass of a substance. Specifically, it is found by dividing the mass by the volume. The unit of density depends upon which units are used to measure mass and volume.

Know More

Mass is a measurement of how much matter there is in a substance. This is often found using the units grams or kilograms. Volume is a measurement of how much space a substance occupies. Cubic centimeters and cubic meters are typical units of volume. Therefore, density is commonly identified using the units grams per cubic centimeter or kilograms per cubic meter. Less commonly, density units reflect the American measurement system, so the label pounds per cubic foot is used.

Density is the mass of a substance per unit volume. The density of water is 1 gram per milliliter. Substances with densities above 1 gram per milliliter sink in water, while substances with densities below 1 gram per milliliter float.

Density is a derived unit because it is calculated from mass and length, which are both base units. Density for an object or substance is defined as mass divided by volume, where volume is defined as length cubed.

The density of a pencil varies based on the type of pencil, but it can be found by measuring the pencil's mass, preferably in grams, and then dividing the mass by the volume. The formula for density is density = mass/volume.
