1. What is m3 to Tonnes Aggregate Calculator?

Definition: This calculator converts volume in cubic meters to weight in tonnes for aggregates (e.g., gravel, sand).

Purpose: It helps construction professionals and material suppliers quickly convert between volume and weight measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Weight in tonnes
• \( V_{m3} \) — Volume in cubic meters
• \( \rho \) — Density in kg/m³ (1482 kg/m³ default for gravel)

Explanation: The volume is multiplied by material density to get kilograms, then divided by 1000 to convert to tonnes.

3. Importance of Volume to Weight Conversion

Details: Accurate conversions are essential for material ordering, transportation planning, and cost estimation in construction projects.

4. Using the Calculator

Tips: Enter the volume in cubic meters and material density (default 1482 kg/m³ for gravel). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is density important in this calculation?
A: Different materials have different densities, so the same volume will weigh differently depending on the material type.

Q2: What's a typical density for common aggregates?
A: Gravel ~1482 kg/m³, Sand ~1600 kg/m³, Crushed stone ~1682 kg/m³, but always verify for specific materials.

Q3: How accurate is this conversion?
A: Accuracy depends on the precision of your density value and material consistency. Moisture content can affect density.

Q4: Can I use this for other materials besides aggregates?
A: Yes, as long as you know the material's density in kg/m³, you can use this for any material.

Q5: Why divide by 1000?
A: This converts kilograms to metric tonnes (1 tonne = 1000 kg).
