Idea behind unit conversion

Mass = Volume x Density = Area x Thickness x Density what follows is that

Specific weight = Mass/Area = Thickness x Density (all units mast match)

Mass/Area for 1 m thick plate in kg/m2 = 1 m * 1 kg/m3

If I want to use mm as thickness 1 mm = 1/1000 m

Mass/Area for 1 mm thick plate in kg/m2 = 1/1000 m * 1 kg/m3 = Density/1000 per mm thickness

Brass density is between 8400 - 8700 kg/m3 means 1 m2 plate that is 1 mm thick weighs min. 8400/1000 = 8.4 kg and 8.4 = Ratio

Here Brass Ratio is 8.5 that means you take a density value or 8500 kg/m³

For x mm of plate you need to multiply x with the Ratio to get kg/m2 units.

Lets say you have y square meters of x mm plate. The total weight (kg) = x * Ratio * y

There's no Density in the formula
