Machining Material Density Chart – Density Unit Conversion Table

2024.6.13

The density of a material is critical in CNC machining and engineering, to save you time for searching and converting densities of different materials, below we showcase a material density chart with four units.

Why Is Density Important in Engineering and Machining?

– Material selection: density affects the selection of material in engineering, which is crucial for ensuring the performance, safety, and cost-effectiveness of a product or component.
– Structural integrity: denser materials are generally stronger and more rigid than less dense materials, making them more suitable for applications that require high strength and stiffness, such as aerospace and automotive components.
– Machining parameters: density affects cutting speeds, feeds, and depths of cut.
– Thermal properties: density is a factor that influences the thermal properties of a material, such as its specific heat capacity and thermal conductivity. These properties are important for applications that involve heat transfer, such as cooling systems and electronic components.
– Cost: generally, denser materials are more expensive than less dense materials, so selecting a material with the appropriate density is important for balancing performance and cost.
– Safety: materials with a higher density may be more prone to cracking or shattering under impact, making them less suitable for applications that involve high-impact forces, such as safety equipment and protective gear.

How to Convert Density Units?

Here we list different ways of density conversion & calculation.
– g/cm3 to kg/m3: multiply it by 1000
– g/cm3 to lb/in3: multiply it by 0.036127
– g/cm3 to lb/ft3: multiply it by 62.427961
– lb/ft3 to lb/in3: multiply it by 0.00057870368028786
– lb/ft3 to kg/m3: multiply it by 16.01846
– lb/in3 to kg/m3: multiply it by 27,679.90
