The Density from Mass and Volume calculator computes the mean density (?) of an object based on its mass (M) and volume (V).
INSTRUCTION: Choose units and enter the following:
- (M) Mass of Object
- (V) Volume of Object
Density(ρ): The calculator computes the mean density (ρ) of the object in kilograms per cubic meter. However, this can be automatically converted into other density units via the pull-down menu.
The Math / Science
The formula for density is as follows:
where:
- ρ is the density
- M is mass
- V is volume
Which is heavier, a ton of bricks or a ton of feathers? The foolish person reply "the bricks", but the answer is neither. They are the same weight (mass). HOWEVER, their density is wildly different, because the volume of space to contain a ton of feather is much bigger. Since volume is in the denominator of this equation, the density of the larger volume (feathers) is much smaller.
Mass - Volume - Density
The relation ship between density, mass and volume is:
Therefore:
