1. What is Tonnes to m3 Conversion?

Definition: This calculator converts the weight of a material in metric tonnes to its volume in cubic meters based on the material's density.

Purpose: It helps in material estimation, transportation planning, and storage space calculation when working with bulk materials.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_{m3} = \frac{T \times 1000}{\rho} \]

Where:

\( V_{m3} \) — Volume in cubic meters
\( T \) — Weight in metric tonnes
\( \rho \) — Material density in kg/m³

Explanation: The weight in tonnes is converted to kilograms (×1000) and then divided by density to get volume in cubic meters.

3. Importance of Weight to Volume Conversion

Details: Many materials are purchased by weight but need to be measured by volume for application. This conversion is essential for accurate project planning.

4. Using the Calculator

Tips: Enter the material weight in tonnes and its density in kg/m³ (default 1000 for water). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 1000 in the formula?
A: We multiply by 1000 to convert tonnes to kilograms (1 tonne = 1000 kg) for consistent units with density (kg/m³).

Q2: Where can I find material densities?
A: Common densities: Water=1000, Sand=1600, Gravel=1800, Concrete=2400 kg/m³. Check material specifications for exact values.

Q3: Does this work for all materials?
A: Yes, as long as you know the material's density. The formula works for liquids, powders, and solid materials alike.

Q4: How accurate is this conversion?
A: Accuracy depends on the precision of your density value. Actual volume may vary with temperature, compaction, and moisture content.

Q5: Can I convert back from m3 to tonnes?
A: Yes, use the inverse formula: \( T = \frac{V_{m3} \times \rho}{1000} \).
