Use this density converter to switch between metric, laboratory, UK imperial, and US customary density units without changing pages.
It is built for science, engineering, materials, and fluid calculations where density values often move between metric, laboratory, and imperial unit systems.
Open focused conversion pages for the most useful density pairs.
Enter a non-negative density value, choose the unit you are starting with, then choose the unit you want to convert to. The result updates instantly as you type or change either unit.
Use the swap button to reverse the selected units when you want to check the same density in the opposite direction.
ConverterKey stores density internally as kg/m³. To convert between two density units, multiply the input by the source unit's kg/m³ factor, then divide by the target unit's kg/m³ factor.
For the default kg/m³ to g/cm³ direction, the formula is value × 0.001. This also supports common searches like kg/m3 to g/cm3, g/ml to kg/m3, and lb/ft3 to kg/m3.
Density connects mass and volume, which makes it useful when comparing liquids, metals, plastics, powders, and other materials. A value in g/mL may be convenient in a lab, while kg/m³ is common in engineering references.
For fluid and material work, keep the unit label with the number. A density written as 1 g/cm³ is the same physical density as 1000 kg/m³, but the scale can look very different if the unit is missing.

Density is mass divided by volume. It describes how much material is packed into a given space, commonly written as kg/m³, g/cm³, g/mL, or lb/ft³.
Multiply the g/cm³ value by 1000. For example, 2.5 g/cm³ equals 2500 kg/m³.
Yes. One milliliter is equal to one cubic centimeter, so 1 g/mL is the same density as 1 g/cm³ and 1000 kg/m³.
Fresh water is about 1000 kg/m³, 1 g/cm³, 1 g/mL, or 62.4 lb/ft³ near room temperature. The exact value changes slightly with temperature and impurities.
Use kg/m³ for SI engineering, science, and most metric references. Use lb/ft³ when working with US customary engineering tables, building materials, or local specifications that already use imperial units.
