Basically, density can be calculated by dividing the mass of an object by its volume.
If you have the DensityScreenScale or the bar testing set GAX1000, then you can use our calculation tool for this. To do this, measure the weight in air and the weight in water with the density scale. You can enter these two values into the tool and it will give you the density. In addition, with the calculation tool you have comparative values of some alloys and many pure metals.
If you want to calculate the density yourself, the formula is:
Density [g/cm³] = Air value [g] / (Air value [g] - Water value [g])
