\ The units for densityĪlthough the standard unit for mass is kilograms (kg) and for volume is cubic metres (m 3 ), in many laboratory situations the norm is finding the mass in grams (g) and volume in cubic centimetres (cm 3 ).Ĭalculating density using grams and centimetres cubed would give a density unit of grams per centimetre cubed (g/cm 3 ). What is the density of a material of 0.45 cubic metres (m 3 ) if it has a mass of 0.2 kg? volume ( V ) is measured in metres cubed (m 3 ).mass ( m ) is measured in kilograms (kg).density ( ρ ) is measured in kilograms per metre cubed (kg/m 3 ).Materialĭensity in grams per cubic centimetre (g/cm³)ĭensity can be calculated using the equation: Scientists can find the density of a material by measuring the mass of a certain volume of the material, for example, one cubic centimetre. A piece of iron with the same dimensions as a piece of aluminium will be heavier because the atoms are more closely packed. For more information on this feature please contact us.Density also depends on the material. This power supply feature, available with Compak™ Pro, automatically adjusts the power level to ensure consistent watt density is applied regardless of the line speed. Most converters who have lines that ramp up and down will incorporate watt density control. As you can see from the watt density formula above if you apply constant power over different line speeds your applied watt density will be different. Most power supplies are set-up to operate on a constant kW output. If my line speed varies how can I be sure I am applying the same amount of surface treatment to the substrate?
