You need to know the density of the substance.
To convert between mass and volume you need the density of the substance. Density = mass/volume. It is not clear what you mean by count. If you are thinking of large scale objects then if they are all alike, you can convert mass to count if you know the mass of one of them. I wonder if you are thinking of chemical quantity expressed in moles? The conversion in this case is moles = mass/molar mass.
The volume and mass need to be calculated from measurements, but they are not read.
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.
It depends on what measurements are given. Density is mass per unit volume.
No. Volume can normally be worked out from measurements. Mass is irrelevant.
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).
Mass and volume are the two measurements that make up density. Density is calculated by dividing an object's mass by its volume.
volume = mass/density and density = mass/volume
This cannot be sensibly answered. Milliliters is a measure of volume and mg is a measure of weight or mass.
Sugar can be measured in both mass (grams) and volume (cups). The mass of sugar is typically used in baking recipes to ensure accurate measurements, while volume measurements are more common in everyday cooking.
Cubic feet is a measure of volume; kilogram is a unit of mass. You don't convert that.Cubic feet is a measure of volume; kilogram is a unit of mass.

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.
