Grams per cm³ Density Calculator

About the Grams per cm³ Density Calculator

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.

When This Page Helps

This calculator improves speed and consistency while reducing avoidable mistakes in practical workflows.

How to Use the Inputs

1. Enter the mass of your material.
2. Select the mass unit (grams, kg, lb, or oz).
3. Enter the volume.
4. Select the volume unit (cm³, mL, L, in³, ft³, or m³).
5. Choose what to solve: density, volume, or mass.
6. Review results including density in multiple units, specific gravity, and buoyancy.
7. Use presets for common materials like water, gold, iron, or ethanol.

Example Calculation

Tips & Best Practices

• Check that all inputs use the same scale and assumptions before trusting the result.
• Compare the answer with the worked example or a rough estimate to catch entry mistakes.

When To Use This Calculator

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. Use it when you need a repeatable calculation in the physics / general category and want the setup, result, and supporting values kept together. This is especially helpful when small input changes, unit choices, or rounding decisions can change the final number.

How To Check The Result

Start by confirming that the inputs match the formula shown on the page. Then compare the main output with the worked example and any secondary values shown by the calculator. If the result will be used in another calculation, keep extra precision until the final step and record the assumptions beside the number.

Practical Notes

Treat the result as a calculation aid rather than a substitute for context. For schoolwork, include the formula and substitution steps. For planning, technical, financial, or health-related decisions, verify important numbers against primary records, current rules, or a qualified professional before acting on them.

Frequently Asked Questions

• What is g/cc?

  Grams per cubic centimeter — the CGS unit of density. 1 g/cc = 1 g/cm³ = 1 g/mL (for liquids).

• How do I convert g/cm³ to kg/m³?

  Multiply by 1000. So 2.7 g/cm³ (aluminum) = 2700 kg/m³.

• What is specific gravity?

  The ratio of a material's density to water's density. SG = 2.7 means 2.7× as dense as water.

• Why does density matter?

  It determines buoyancy, material selection in engineering, quality control in manufacturing, and identification of unknown materials.

• Does temperature affect density?

  Yes — most materials expand when heated, decreasing their density. Water is unusual: it is densest at 4°C.

• Is cm³ the same as mL?

  Yes, by definition. 1 cm³ = 1 mL exactly.
