About

Converting volume to mass is not a direct unit conversion; it is a physical calculation dependent on the substance's density. One cubic meter of feathers weighs significantly less than one cubic meter of lead. This tool bridges that gap by integrating a density database.

Essential for shipping logistics (calculating cargo weight from container volume) and structural engineering (determining load from material volume), this calculator applies the formula m = V × p. It handles unit standardization automatically, converting your input volume (Liters, Gallons) into cubic meters before applying the density factor of the selected material.

Formulas

The relationship between Mass, Volume, and Density is defined as:

Mass = Volume × Density

This tool normalizes inputs to standard SI units before calculation:

m_kg = V_m3 × ρ_kg/m3

Frequently Asked Questions

Volume is space; Mass is the amount of matter. To convert between them, you must know how tightly packed the matter is. This property is Density. Without density, the conversion is impossible.

Select "Custom Density" from the dropdown and manually enter the density value in kg/m³ if you know it from a safety data sheet (SDS) or specification.

Yes. Most liquids expand when heated, lowering their density. The values provided here are generally at standard temperature (20°C / 68°F). For high-precision chemical engineering, apply temperature correction factors.
