Enter the mass and density into the calculator to determine the volume. This calculator can also evaluate any of the variables given the others are known.

Kg To Mm Formula

The following formula can be used to convert kilograms to millimeters for a specific substance, given its density.

V = M / ρ


  • V is the volume (mm^3)
  • M is the mass (kg)
  • ρ is the density of the substance (kg/mm^3)

To calculate the volume in millimeters, divide the mass in kilograms by the density of the substance in kilograms per cubic millimeter. Please note that this formula assumes that the substance is homogeneous and its density is constant.

What is a Kg To Mm?

Kg to mm is not a valid conversion as they are measurements of two different quantities. Kg (kilogram) is a unit of mass in the International System of Units (SI) while mm (millimeter) is a unit of length in the same system. Therefore, it is not possible to convert kilograms to millimeters directly without additional information such as density for a specific substance.

How to Calculate Kg To Mm?

The following steps outline how to calculate the Kg To Mm using the formula V = M / ρ.

  1. First, determine the mass (M) in kilograms (kg).
  2. Next, determine the density of the substance (ρ) in kilograms per cubic millimeter (kg/mm^3).
  3. Next, use the formula V = M / ρ to calculate the volume (V) in cubic millimeters (mm^3).
  4. Finally, calculate the Kg To Mm.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

mass (M) = 5 kg

density of the substance (ρ) = 2 kg/mm^3
