Read US short tons and metric tonnes as different mass units.
Can the word ton be copied directly from one supplier quote to another?
Use the matching calculator
Use this decision sequence
- Identify the exact mass unit used by each quote.
- Normalise both masses to kilograms or pounds using the same stated unit definitions.
- Apply density only when converting between mass and an applicable volume basis.
- Compare delivered quantities and prices after units are explicit.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| US short ton | 2,000 pounds. |
| Metric tonne | 1,000 kilograms. |
| Density | Needed for mass-to-volume conversion, not for mass-unit conversion. |
Worked comparison
An illustrative 2,000 lb delivery is one US short ton but approximately 907.185 kg, or 0.907185 metric tonne. Calling it one metric tonne overstates delivered mass by roughly 10.23% relative to the original delivery. A separate density input is needed only if the order is compared with cubic yards or cubic metres.
Check before using the estimate
Do not assume supplier terminology; read the actual unit basis and delivered quantity in the quote.
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.
Sources and product references
References support the stated product-data distinction. All worked examples are independent illustrative arithmetic.
