What Is Density Converter?
A Density Converter is a tool that translates between different units of mass per volume, enabling accurate calculations and conversions across various fields. It is commonly used by engineers, researchers, and scientists in materials science, chemistry, fluid mechanics, and manufacturing to ensure precise measurements and comparisons. One specific problem it solves is the conversion of density units from kg/m3 to g/cm3, which is crucial in lab work and everyday materials analysis.
The tool supports conversions between five different units: kg/m3, g/cm3, lb/ft3, lb/in3, and kg/L, with predefined reference values for each unit pair. For instance, it can convert lb/ft3 to kg/m3 using a factor of 16.018463374, allowing users to easily switch between imperial and metric systems. What makes this tool different is its ability to handle specific conversions like kg/m3 to g/cm3 with a factor of 1000, or kg/L to g/cm3 with a direct equivalence.
It also allows for the conversion of units like lb/in3 to g/cm3 using a factor of 27679.9047, demonstrating its capability to handle a wide range of density unit conversions, including specific gravity to density calculations. By providing accurate and reliable conversions, it facilitates precise calculations in various fields, from materials science to fluid mechanics, making density unit conversion more efficient and convenient for users working with different units like kg/m3, g/cm3, or lb/ft3.

Technical Guide
All unit conversions below reference kg/m³, the SI standard for density.
• 1 g/cm³ = 1,000 kg/m³ = 1 kg/L
• 1 lb/ft³ = 16.0185 kg/m³
• 1 lb/in³ = 27,679.9 kg/m³
Common densities:
• Water: 1.000 g/cm³ = 1,000 kg/m³
• Air (sea level): 1.225 kg/m³
• Steel: 7.8 g/cm³
• Aluminum: 2.7 g/cm³
• Gold: 19.3 g/cm³
Specific gravity is the ratio of a material's density to water's density. Since water is 1 g/cm³, specific gravity numerically equals density in g/cm³.
Tips & Best Practices
-
1Water is the reference: 1 g/cm³ = 1 kg/L = 1,000 kg/m³.
-
2Specific gravity equals density in g/cm³ (relative to water at 4°C).
-
3Objects float if their density is less than the fluid they are in.
-
4g/cm³ and kg/L are numerically identical.
