About

Converting mass (tons) to volume (cubic meters) is physically impossible without knowing the density of the specific material. Unlike converting kilometers to miles, which uses a fixed constant, this conversion relies on the variable ρ (density). A ton of lead occupies significantly less space than a ton of feathers.

This tool integrates a database of standard bulk densities for construction and industrial materials. Contractors ordering aggregate, logistics managers planning shipping container loads, and engineers calculating tank capacities rely on these averages. However, moisture content and compaction rates can alter density by 10-15%. Always verify specific gravity with the supplier for critical pours.

Formulas

The calculation divides the mass by the material density.

V_m³1 = m_tρ_t/m³

Where ρ is the bulk density of the chosen material.

Frequently Asked Questions

Sand density depends heavily on moisture content and grain size. Dry loose sand might be 1.4 t/m³, while wet packed sand can reach 2.1 t/m³. This tool uses standard averages for "loose" and "wet" conditions.

Select "Custom Density" from the dropdown. You can then manually enter the specific gravity or density provided on your material's safety data sheet (SDS).

At 4°C, pure water is exactly 1.0 t/m³. However, seawater is denser (approx 1.025 t/m³), and hot water is slightly less dense. For general purposes, 1.0 is the standard.

No. This calculates solid volume based on density. When excavating soil, the volume expands (bulking). You should apply a bulking factor (usually 1.2 to 1.3) to the result if calculating excavation removal.
