Convert density between g/cm³ and kg/m³: 1 g/cm³ = 1,000 kg/m³ (water = 1 g/cm³). For engineering, chemistry and science — free and accurate.
Density relates mass and volume — how "compact" a substance's matter is — and its discovery as a measurable concept traces back to one of the most retold stories in ancient science: the legend of Archimedes, in the 3rd century BCE, who reportedly discovered the principle upon noticing that water level rose proportionally to the volume of his body submerged in a bathtub, allowing him to detect fraud in gold objects without damaging them. This same principle still underpins essential modern applications: it explains why steel ships, far denser than water alone, manage to float (the average density of the hull plus internal air is lower than water's), and it's the basis of industrial quality control tests that identify materials and detect adulteration without complex chemical analysis. This converter calculates between kilograms per cubic metre (the standard SI unit), grams per cubic centimetre (more common in labs), pounds per cubic foot, and other density units, relevant for materials engineers assessing component strength and weight, chemists identifying unknown substances, mining and metallurgy industry professionals, and any technical context where the relationship between a material's weight and volume needs to be calculated precisely.
Multiply the value in g/cm³ by 1000.
The density of pure water at 4°C is 1000 kg/m³ or 1 g/cm³.
It is the relationship between the mass of a material and the volume it occupies.
The petroleum, civil, and pharmaceutical industries routinely use density conversion.
Yes, we apply the standard conversion factors recommended by international bodies.
