Convert between mass, volume, and density in g/cm³ (g/cc), kg/m³, and lb/ft³. Includes a material density reference table and buoyancy check.
Density — mass per unit volume — is one of the most fundamental physical properties of matter. Expressed in grams per cubic centimeter (g/cm³ or g/cc), it tells you how much material is packed into a given space. Water has a density of exactly 1.0 g/cm³ at 4°C, making it the universal reference for the specific gravity of solids and liquids.
This Grams per cm³ Density Calculator lets you compute density from mass and volume, find the volume of a known mass at a known density, or find the mass that fills a given volume. It supports grams, kilograms, pounds, and ounces for mass, and cm³, mL, liters, in³, ft³, and m³ for volume.
Beyond the basic calculation, the tool shows the density in multiple unit systems (g/cm³, kg/m³, lb/ft³), computes the specific gravity relative to water, and tells you whether the material floats or sinks — along with the Archimedes submersion depth. A visual bar chart compares your material to reference densities, and a comprehensive table lists densities for common materials from air to gold.
This calculator improves speed and consistency while reducing avoidable mistakes in practical workflows. This tool is designed for quick, accurate results without manual computation. Whether you are a student working through coursework, a professional verifying a result, or an educator preparing examples, accurate answers are always just a few keystrokes away.
Density: ρ = m / V Specific Gravity: SG = ρ_material / ρ_water = ρ / 1.0 g/cm³ Submersion: % submerged = (ρ_object / ρ_fluid) × 100 (if ρ_object < ρ_fluid) Conversions: 1 g/cm³ = 1000 kg/m³ = 62.428 lb/ft³
Result: Density = 1.0000 g/cm³, SG = 1.0, Floats: No (equals water)
100 grams in 100 cm³ gives exactly 1.0 g/cm³ — the density of water.
Use consistent units throughout your calculation and verify all assumptions before treating the output as final. For professional or academic work, document your input values and any conversion standards used so results can be reproduced. Apply this calculator as part of a broader workflow, especially when the result feeds into a larger model or report.
Most mistakes come from mixed units, rounding too early, or misread labels. Recheck each final value before use. Pay close attention to sign conventions — positive and negative inputs often produce very different results. When working with multiple related calculations, keep intermediate values available so you can trace discrepancies back to their source.
Enter the most precise values available. Use the worked example or presets to confirm the calculator behaves as expected before entering your real data. If a result seems unexpected, compare it against a manual estimate or a known reference case to catch input errors early.
Grams per cubic centimeter — the CGS unit of density. 1 g/cc = 1 g/cm³ = 1 g/mL (for liquids).
Multiply by 1000. So 2.7 g/cm³ (aluminum) = 2700 kg/m³.
The ratio of a material's density to water's density. SG = 2.7 means 2.7× as dense as water.
It determines buoyancy, material selection in engineering, quality control in manufacturing, and identification of unknown materials. Use this as a practical reminder before finalizing the result.
Yes — most materials expand when heated, decreasing their density. Water is unusual: it is densest at 4°C.
Yes, by definition. 1 cm³ = 1 mL exactly.
