Some facts

  • ⓘ Remember: Density is the physical quantity that determines the ratio beetwen the mass and the volume that mass occupies.
  • We usually denote the density by d or the small Greek letter ρ (pronunciation: rho).
  • If the sample body has mass m and it occupies volume V, then the density of the substance from which it is composed can be calculated using the following formula:
    d=mVd = \dfrac{m}{V}
    • d = density,
    • m = mass,
    • V = volume.
  • The density unit in SI system is kilogram per cubic meter:
  • Density is a feature of a particular substance. An example of a relatively high density substance is steel. Example of relatively small density is styrofoam, .
    ⓘ Example: If we grab a small steel ball in hand, we can easily feel it's weight. If we grab anologous (i.e. with the same size), but made of styrofoam ball in second hand, then we notice that it is much lighter than the previous one. This is because steel has a much higher density than styrofoam.
  • Substances with high density are good acoustic insulators. For example, making the walls of a room with a thick concrete layer (high density material) will cause what is going on inside to be very poorly audible on the outside.
  • Acoustic insulation does not go hand in hand with thermal insulation. For example: styrofoam (very low density material) is known as a very good thermal insulator, but is unusable as an acoustic insulator.
  • ⚠ WARNING! Substances can change their density depending on temperature and pressure. Therefore density tables also contain the conditions in which they were measured.

How to convert

  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
