Metal Density Change Formula & Calculator

Metal Density due to Pressure & Temperature Calculation

α - Material thermal expansion coefficient (K)
p0 - Material density at reference temp (kg/m3)
ΔT - Change in temperature(K)

Metal density change calculator - formula & step by step calculation to find the change of mass due to constant pressure & change of reference temperature. ρ = ρ0/(1 + (α x δT)). Material density at reference temperature ρ0 in kg/m3, material thermal expansion coefficient close to reference temperature α in Kelvin & change of reference temperature δT in Kelvin are the key terms of this calculation. Density is the mass of any material per unit volume.


In mechanical engineering, the below mathematical formula is used to calculate the change of density or mass per unit volume of the metal or material.
