Understanding Density

Density is a measure of mass per unit volume. It is calculated using the formula:

Density = Mass / Volume

This calculator allows you to input mass and volume in various units, converts them to standard units (kilograms for mass and cubic meters for volume), and then calculates the density.

**How to Use the Calculator:**

• Enter the Mass: Input the mass value and select the appropriate unit (kg, g, lb).
• Enter the Volume: Input the volume value and select the appropriate unit (m³, cm³, l).
• Calculate: Click the "Calculate Density" button to get the result in kg/m³.
