Material: River Sand - Coarse (Zone I) | Density: 1,650 kg/m³ | Moisture: Dry
1 m³ = 1,650 kg = 1.65 t = 0.353 brass = 1.819 US tons
What This Means in Practice
1 cubic metres of River Sand - Coarse (Zone I) equals 1 m3 and weighs approximately 1.65 metric tonnes. That is about 0.17 selected truck loads, so plan for 1 load(s).

What Is an Aggregate Unit Converter?
Aggregate suppliers and project drawings often use different units. Indian contractors may receive quotes in brass, US homeowners order cubic yards, UK engineers specify metric tonnes, and Australian delivery notes may show cubic metres. This converter brings those systems together for sand, gravel, crushed stone, and sub-base materials.
Unlike a generic converter, it uses material bulk density to convert between volume and weight. One cubic metre of MOT Type 1 weighs about 1,900 kg, while the same volume of slate chip weighs about 1,420 kg. Using one generic density can make a cross-unit result wrong by nearly 30%.
Contractors, homeowners, engineers, international buyers, and students can convert cubic metres, cubic feet, cubic yards, litres, brass, kilograms, tonnes, quintals, US tons, UK tons, pounds, bags, and truck loads in either direction.
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.

Tips for Using the Aggregate Unit Converter
Always confirm which "ton" your supplier means
US suppliers use short tons at 907 kg. Modern UK suppliers generally use metric tonnes at 1,000 kg, while older specifications and maritime work may use long tons at 1,016 kg. The difference reaches 12%, or about 6 tonnes on a 50-tonne order. Confirm the unit before comparing quotations.
Use density-based conversion instead of fixed approximations
Rules such as multiplying cubic yards by 1.4 use a generic mid-density gravel assumption. Actual results vary substantially between dense MOT Type 1 and lighter decorative gravel. Select the correct material or enter a supplier-tested custom density.
Remember that brass is a volume unit
Five brass means 500 cubic feet or 14.16 m³, not a fixed weight. Five brass of river sand at 1,600 kg/m³ weighs about 22.65 tonnes, while five brass of MOT Type 1 at 1,900 kg/m³ weighs about 26.90 tonnes. Enter brass in the volume section.
Remember that quintal is a weight unit
A metric quintal equals exactly 100 kg. Fifty quintals equal 5,000 kg or 5 tonnes. Volume is then calculated by dividing this weight by the selected material density. Enter quintals in the weight section.
Use truck loads to plan delivery scheduling
An output of 2.3 loads on a 10-tonne truck means three trips are needed and the third is partial. This can help negotiate partial loads, choose another vehicle size, or sequence site deliveries.
Account for moisture when material is delivered wet
Wet aggregate carries water weight, so a truck reaching its payload limit contains less dry material. A nominal 10-tonne wet-sand load may provide only about 8.2 tonnes of dry equivalent. Select Damp or Wet when that reflects actual delivery condition.
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.
