Empirical or geometrical estimation of the void fraction of the volume can be performed in order to arrive at the volume of the substance itself. One should further take into account that this formula is not applicable if the measured volume contains voids (air, vacuum, liquid, gas or solid other than the substance of interest) the calculation would instead result in "bulk density" and not volumetric mass density. If the object is of heterogeneous density a piece-wise approach may be preferred. Determining the density of a gas or liquid may require the use of specialized equipment like a hydrometer, a dasymeter or a Coriolis flow meter. The formula is valid for homogenous materials where the density of all points in the object equals its total mass divided by its total volume. Solving for mass or volume requires straightforward transformations which we used in constructing the density calculator above. The formula for density ( ρ - Greek lower-case letter rho) expressed in terms of the body's volume ( v) and its mass ( m) is the equation: When the output is mass or volume it is in both standard metric units and imperial ones, with the units automatically being adjusted depending on how big or small the resulting value is. Grams or kilograms per litre are also available. The output if calculating density is in grams per cm 3 or kg per m 3, as well as in oz/cu in, lb/cu ft and lb per cubic yard. When solving for mass you need to know volume and density while when solving for volume you need to know the substance's mass and density. The calculator can also be used to solve for any of the other values: mass and volume. Mass density is defined as the ratio of the substance's volume to its mass. number density: the particles per unit volume. It should be differentiated with other kinds of density e.g. The density calculator calculates the volumetric mass density of a substance: the mass concentrations of a pure substance.
#Mass to volume calculator how to#
volume unit - the unit of volume (liters, milliliters, cm 3, etc.),.If you do the other way around (enter the mass of the sample in "mass of sample" field) then the calculated volume will appear here. If you know the volume and want to calculate the mass, enter the volume here. volume of sample - the volume occupied by the sample in the unit of your choice (e.g.
