Conversion Inputs
Moisture affects weight-to-volume conversion. Wet aggregate weighs more for the same volume.

Material: 20mm Crushed Granite | Density: 1,600 kg/m³ | Moisture: Dry
1 m³ = 1,600 kg = 1.6 t = 0.353 brass = 1.764 US tons
What This Means in Practice
1 metric tonnes of 20mm Crushed Granite weighs 1,000 kg and occupies approximately 0.625 m³. That is about 0.1 selected truck loads, so plan for 1 load(s).
0.625 m³
22.072 ft3 / 0.2207 brass
1,000 kg
1 t / 1.1023 US tons
1 load(s)

Convert aggregate tonnes to volume
Weight-to-volume conversion divides kilograms by the selected density.
Denser materials occupy less volume for the same tonne weight.
- Starts with 1 metric tonne.
- Reports m³, ft³, yd³, litres, and brass.
- Change material for supplier-specific estimates.
How Does the Aggregate Unit Converter Work?
1. Volume to volume
Target volume = Source volume x source-to-m³ factor / target-to-m³ factor
1 m³ = 35.3147 ft³ = 1.30795 yd³ = 1,000 litres = 0.3531 brass
These geometric conversions are fixed and do not depend on material.
2. Weight to weight
Target weight = Source weight x source-to-kg factor / target-to-kg factor
1 tonne = 1,000 kg; 1 quintal = 100 kg; 1 US ton = 907.185 kg; 1 UK ton = 1,016.047 kg
US short tons, metric tonnes, and UK long tons are different units and should never be treated interchangeably.
3. Volume to weight
Weight (kg) = Volume (m³) x Bulk density (kg/m³) x Moisture factor
Dry, damp, and wet factors are 1.00, 1.10, and 1.22.
4. Weight to volume
Volume (m³) = Weight (kg) / (Bulk density x Moisture factor)
The selected material density determines how much physical volume a known weight occupies.
5. Bags and truck loads
Bags = ceiling(total kg / bag kg)
Exact loads = total kg / truck capacity kg
Planned loads = ceiling(exact loads)
Bags and planned loads round up because partial delivery units cannot normally satisfy the order.

Scenario 1 — India (Hyderabad)
Supplier quotes 5 brass of 20mm crushed granite — how many tonnes is that?
A South Indian aggregate supplier quotes a price per brass. The structural engineer needs the quantity in metric tonnes for the project cost report. Material: 20mm crushed granite, bulk density 1,600 kg/m³, dry condition.
| Step | Formula / Substitution | Result |
|---|---|---|
| Convert brass → m³ | 5 brass × 2.83168 m³/brass | 14.158 m³ |
| Convert m³ → kg | 14.158 × 1,600 kg/m³ | 22,653 kg |
| Convert kg → tonnes | 22,653 ÷ 1,000 | 22.65 tonnes |
| Convert kg → quintals | 22,653 ÷ 100 | 226.53 quintals |
| Truck loads (10T truck) | 22,653 ÷ 10,000 | 2.27 loads → plan 3 loads |
Scenario 2 — United States (Texas)
Project specifies 15 cubic yards of pea gravel — how many US tons and metric tonnes?
A US homeowner needs pea gravel for a driveway. The project plan uses cubic yards but the supplier quotes per US ton. The owner also needs metric tonnes for comparison with an online calculator. Material: river gravel / pea gravel (20mm), bulk density 1,500 kg/m³, dry condition.
| Step | Formula / Substitution | Result |
|---|---|---|
| Convert yd³ → m³ | 15 yd³ × 0.764555 m³/yd³ | 11.468 m³ |
| Convert m³ → kg | 11.468 × 1,500 kg/m³ | 17,202 kg |
| Convert kg → metric tonnes | 17,202 ÷ 1,000 | 17.20 metric tonnes |
| Convert kg → US short tons | 17,202 ÷ 907.185 | 18.96 US tons |
| Convert m³ → brass | 11.468 ÷ 2.83168 | 4.05 brass |
Scenario 3 — United Kingdom (Birmingham)
Engineer specifies 8 tonnes of MOT Type 1 — how many bulk bags and what volume?
A homeowner receives an engineer's specification for 8 metric tonnes of MOT Type 1 sub-base. They want to know how many 850 kg bulk bags to order and what volume that represents, to verify their driveway area estimate. Material: MOT Type 1 / crusher run, bulk density 1,900 kg/m³, dry condition.
| Step | Formula / Substitution | Result |
|---|---|---|
| Convert tonnes → kg | 8 × 1,000 | 8,000 kg |
| Convert kg → bulk bags (850 kg) | ceiling(8,000 ÷ 850) | 10 bulk bags (9.41 exact, rounded up) |
| Convert kg → m³ | 8,000 ÷ 1,900 kg/m³ | 4.211 m³ |
| Convert m³ → ft³ | 4.211 × 35.3147 | 148.7 ft³ |
| Convert m³ → yd³ | 4.211 ÷ 0.764555 | 5.51 yd³ |
How the converter handles each conversion pathway
| You enter | Conversion path | Needs density? | Example |
|---|---|---|---|
| Volume (m³, ft³, yd³, brass, litres) | → all other volume units | No — fixed ratios | 5 brass = 14.16 m³ = 500 ft³ |
| Volume (any) | → all weight units | Yes — multiplies by density | 14.16 m³ × 1,600 = 22,656 kg |
| Weight (kg, t, quintal, US ton, UK ton, lb) | → all other weight units | No — fixed ratios | 1 tonne = 1,000 kg = 10 quintals |
| Weight (any) | → all volume units | Yes — divides by density | 8,000 kg ÷ 1,900 = 4.21 m³ |
Volume ↔ volume and weight ↔ weight conversions are independent of material selection. Only volume ↔ weight conversions depend on the selected material's bulk density. Selecting the wrong material only affects the cross-domain conversions — not the within-domain ones.
Converter Limitations & Assumptions
- Bulk densities are material-specific but not quarry-specific. Local material can vary by 3-8% because of source rock, grading, and particle shape. For orders above about 50 tonnes, obtain a tested density and use Custom.
- Brass is an informal Indian construction volume unit equal to 100 cubic feet or 2.83168 m³. It is not an IS or international standard unit, even though its customary definition is consistent.
- This converter uses the metric quintal of 100 kg used in India. Historical hundredweight or regional units with similar names are not supported.
- Damp factor 1.10 and Wet factor 1.22 are typical averages. Actual moisture varies with weather, source, and storage. Concrete batching should use measured aggregate moisture.
- The bulk-bag output assumes 850 kg. Suppliers may use 800 kg, 900 kg, or 1,000 kg bags, so verify the stated bag weight before ordering.
- Truck loads are calculated from payload weight only. Low-density material may fill the truck body before reaching its legal weight capacity, so also verify vehicle volume capacity.
