Enter the metal mass (kg) and the metal volume (m^3) into the Metal Density Calculator. The calculator will evaluate and display the Metal Density. 

Metal Density Formula

The following formula is used to calculate the Metal Density. 

Dm = MM / mV
  • Where Dm is the Metal Density (kg/m^3)
  • MM is the metal mass (kg) 
  • mV is the metal volume (m^3) 

How to Calculate Metal Density?

The following example problems outline how to calculate Metal Density.

Example Problem #1:

  1. First, determine the metal mass (kg).
    1. The metal mass (kg) is given as: 65.
  2. Next, determine the metal volume (m^3).
    1. The metal volume (m^3) is provided as: 10.
  3. Finally, calculate the Metal Density using the equation above: 

Dm = MM / mV

The values given above are inserted into the equation below:

Dm = 65 / 10 = 6.5 (kg/m^3)


What is metal density and why is it important?

Metal density is a measure of how much mass a metal has in a given volume, typically expressed in kilograms per cubic meter (kg/m^3). It is important because it helps in identifying the type of metal, its quality, and its applications in various industries such as construction, automotive, and aerospace. High-density metals are often used for their strength and durability, while low-density metals are preferred for their lightweight properties.

How can the metal density affect the choice of metal for a specific application?

The density of a metal can significantly affect its selection for a particular application. For example, in the aerospace industry, low-density metals such as aluminum and titanium are preferred for their lightweight properties, which contribute to fuel efficiency. In contrast, high-density metals like steel and tungsten are favored in construction and manufacturing for their strength and durability. The choice of metal depends on the balance between weight, strength, and cost considerations specific to the application.

Can metal density change with temperature or pressure?

Yes, metal density can change with temperature and pressure, although the changes are usually small for solids. As temperature increases, metals tend to expand, leading to a decrease in density. Conversely, applying pressure can compress the metal, increasing its density. However, these effects are generally minimal for most practical applications, and standard density values are typically sufficient for engineering calculations.
