Check tare and packing basis in a bulk density sample.
Does the density sample represent the same material state as the order?
Use the matching calculator
Use this decision sequence
- Measure the empty sample container mass separately.
- Measure filled volume consistently and subtract tare from filled mass.
- Record whether the sample is loose, placed, wet or dry.
- Apply the derived density only to an order volume on a comparable basis.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| Filled sample mass | Includes container tare. |
| Sample net mass | Filled mass minus tare. |
| Comparable volume basis | Essential before using density for another quantity. |
Worked comparison
An illustrative 0.02 m³ sample weighs 34 kg with a 2 kg container. Its net 32 kg yields 1,600 kg/m³. Including tare instead gives 1,700 kg/m³, a 6.25% overestimate. Applying either value to 1.5 m³ gives different masses, and neither is valid if the sample’s packing or moisture differs materially from the delivery basis.
Check before using the estimate
A user sample is not a certified universal property for gravel, sand or soil.
All dimensions, product properties, prices and specifications in this example are illustrative arithmetic inputs. Use the values from your measured plan, selected product data sheet and supplier quote. This guide does not choose construction specifications or certify safety.
