It depends on what you wish to convert it to!
I think height times width.
Density= mass/volume volume = mass/density
volume = mass/density and density = mass/volume
The density of the substance is required to convert volume to mass or mass to volume
density = mass / volume density x volume = mass volume = mass / density
To convert density to mass, you need to know the volume as well. The formula to calculate mass from density and volume is mass = density x volume. Multiply the density of the substance by the volume in cubic units to get the mass in units of mass (e.g. grams, kilograms).
To convert mass to volume, you need to know the density of the material. The formula for this calculation is: Volume = Mass / Density. This formula allows you to determine how much space a specific mass of a substance will occupy based on its density.
(Mass) divided by (volume).
Mass is the amount of matter in an object, volume is the amount of space the object occupies, and density is the mass per unit volume. The relationship between these properties can be described by the equation density = mass/volume. Objects with higher density have more mass packed into a smaller volume, whereas objects with lower density have less mass spread out over a larger volume.
Density is by definition mass divided by volume. Therefore volume times density equals mass. Diving both sides of that equation by the density, we get volume equals mass divided by density. So the answer to your question is, divide the mass by the density.
You cannot. Density = Mass/Volume so without the volume of the substance in question, you cannot convert mass into density.
If you don't have the volume, you cannot directly convert density into mass. The formula for density (density = mass / volume) requires both mass and volume to calculate. You will need either the volume or another piece of information to determine the mass.
