Density Conversion: A Comprehensive Guide from g/cm³ to kg/m³

Introduction

Density, a fundamental physical property, quantifies the mass of a substance per unit volume. Understanding the conversion between different density units is crucial in various fields, including physics, chemistry, engineering, and life sciences. This comprehensive guide will delve into the conversion of density from grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³).

Understanding the Units

• Grams per cubic centimeter (g/cm³): This unit expresses the mass of a substance in grams relative to its volume in cubic centimeters. It is commonly used to measure the density of solids and liquids.
• Kilograms per cubic meter (kg/m³): This unit expresses the mass of a substance in kilograms relative to its volume in cubic meters. It is widely used in the construction industry, fluid mechanics, and environmental studies.

Formula for Density Conversion

The conversion between g/cm³ and kg/m³ is straightforward using the following formula:

Density (kg/m³) = Density (g/cm³) x 1000

This formula is derived from the fact that 1 kilogram (kg) is equal to 1000 grams (g) and 1 cubic meter (m³) is equal to 100 cubic centimeters (cm³).

Example Conversion

Suppose you have a substance with a density of 2 g/cm³. To convert this density to kg/m³, we use the formula:

Density (kg/m³) = 2 g/cm³ x 1000 = 2000 kg/m³

Therefore, the density of the substance in kg/m³ is 2000.
