Material Density
Opacity increases with density.
Understanding Density
Density ($\rho$) is a measure of how much mass is contained in a given volume. Pure water has a density of 1,000 kg/m³, while gold is much denser at approximately 19,300 kg/m³.

How to Use
- 1Select the variable you want to solve for: Density, Mass, or Volume.
- 2Enter the two known values.
- 3The result serves as a fundamental physical property of the material.
Formula & Logic
Density is defined as mass per unit volume. It is a measure of how tightly matter is crammed together.
Practical Applications
Material Identification
Identify unknown substances (like gold vs. pyrite) by calculating their density.
Buoyancy
Determine if an object will float in water; if it is less dense than water (1 g/cm³), it floats.
Shipping
Calculate the weight of a shipment based on the volume of the container and the density of the cargo.
Frequently Asked Questions
Q.What is the density of water?
Pure water has a density of approximately 1 g/cm³ or 1000 kg/m³ at 4°C.
Q.Does temperature affect density?
Yes. For most substances, density decreases as temperature increases because objects expand (volume increases) when heated.
Q.How do I convert g/cm³ to kg/m³?
Multiply by 1000. For example, 7.8 g/cm³ (density of steel) is equal to 7800 kg/m³.
