Density Converter
Density Converter changes a density value between kg/m^3, g/cm^3, g/mL, lb/ft^3, and lb/in^3 and shows the converted value.
What this calculator does
The Density Converter estimates your result instantly from the values you enter, using standard science & engineering formulas. Density Converter changes a density value between kg/m^3, g/cm^3, g/mL, lb/ft^3, and lb/in^3 and shows the converted value. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Density Converter
The Density Converter restates a density in a different unit across metric and imperial systems.
Every unit is scaled to a base of kg/m³ first, so conversions between g/cm³, g/mL, lb/ft³, and lb/in³ stay consistent.
Formula & Mathematical Calculation
Converted Value = f(Density value, From, To)
Calculated according to standard science formulas implemented in the calculator core.
Calculation Example
Convert 1 g/cm³ (the density of water) to kg/m³.
base = 1 × 1000 = 1000, then result = 1000 ÷ 1 = 1000 kg/m³.
Key Benefits
- Converts across five metric and imperial density units
- Uses a common kg/m^3 base for consistent results
- Treats g/cm^3 and g/mL as equal, both 1000 kg/m^3
- Result shown to six decimal places
How to Use this Calculator

Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- Density Converter produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
