Density | Definition, Symbol, Units, Formula, & Facts | Britannica
2024年12月21日 · density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per
Density - Wikipedia
Density (volumetric mass density or specific mass) is a substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.
Unit of Density - Density Definition, SI unit, Solved Examples
Density Definition: Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Symbol: D or ρ: Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
