First you need to calculate mass.
mass = volume x densityIn other words, you need to know the density for the specific material - there is simply no standard conversion between volume and mass.
The above formula will give you the mass, for example in kilograms; if you really want the weight (for example, in newtons), you need to multiply the mass times the gravity, which is about 9.8 newton/kilogram in SI units.
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
by multiplying
To calculate weight or mass when diameter and height are given, you first need to calculate the volume of the object using the formula for the volume of the shape (e.g., cylinder, sphere). Once you have found the volume, you can then calculate the weight or mass by multiplying the volume by the density of the material. Weight can be calculated using the formula Weight = mass x gravity.
You calculate its volume, look up the density of bronze, then multiply volume x density to get mass. Probably that's what you want; if you really want weight, you multiply mass x gravity to get the weight.
Kilogram is weight, not volume.
you subtract the weight of the water from the weight of the measuring cylinder and you get the volume of the stone
Mineral density should know. Weight / density = volume
To calculate the weight of an object when the volume is known, you would also need the density of the material the object is made of. By multiplying the volume of the object by its density, you can determine the weight of the object.
To calculate the weight of EN-24 steel, you need to know the volume of the steel and its density. The formula to calculate weight is Weight = Volume x Density. The density of EN-24 steel is around 7.85 grams per cubic centimeter.
Volume occupied divided by weight
Density is weight divided by volume. Measure the weight (with a scale), calculate the volume (which is easy to do if the foam is rectangular in shape - you might even want to cut out a rectangular piece, if your foam has an irregular shape), and divide the weight by the volume.
To calculate dry density from the weight of wet sediment, you need to first determine the volume of the wet sediment. You can do this by dividing the weight of the wet sediment by the bulk density of the sediment. Once you have the volume of the wet sediment, you can then calculate the dry density by dividing the weight of the wet sediment by the volume of the wet sediment.
