About Density Converter (kg/m³, g/cm³, lb/ft³)

The Density Converter helps you convert between common density units such as kilograms per cubic meter (kg/m³), grams per cubic centimeter (g/cm³), and pounds per cubic foot (lb/ft³). It’s especially useful in physics, chemistry, and engineering applications.

Formula (Simple Explanation)

1 g/cm³ = 1000 kg/m³ = 62.43 lb/ft³

Each unit measures mass per unit volume. The conversion is based on metric and imperial relationships between kilograms, grams, and pounds, and between cubic meters, centimeters, and feet.

Example:

Input: Convert 2.5 g/cm³ to kg/m³

Output: 2.5 × 1000 = 2500 kg/m³

Steps to Use:

  1. Select the input unit (kg/m³, g/cm³, or lb/ft³).
  2. Enter the density value you want to convert.
  3. Choose the unit you want to convert to.
  4. Click 'Convert' to get the result instantly.

Frequently Asked Questions

What is density?

Density is the measure of mass per unit volume. It tells how much mass is packed into a given space, usually expressed in kg/m³, g/cm³, or lb/ft³.

How do I convert g/cm³ to kg/m³?

Multiply the value in g/cm³ by 1000. For example, 2.5 g/cm³ × 1000 = 2500 kg/m³.

How do I convert kg/m³ to lb/ft³?

Multiply the value in kg/m³ by 0.06243 to get lb/ft³. For example, 1600 kg/m³ × 0.06243 = 99.89 lb/ft³.

Which density unit is used in physics?

The standard SI unit for density is kilograms per cubic meter (kg/m³). However, g/cm³ is often used in laboratory work, and lb/ft³ is common in the U.S. system.

Why does density vary with temperature?

As temperature increases, most substances expand, decreasing their density. This is why hot air rises and cold water sinks.
