Description
Multiply nonnegative recordedTonnage by positive suppliedBaseUnitsPerTon and return the nonempty source label unchanged.
A supplied unit factor translates a quantity to a declared target basis. Historical and laboratory unit names can conceal different regional or material-specific definitions.
Multiply nonnegative recordedTonnage by positive suppliedBaseUnitsPerTon and return the nonempty source label unchanged.
When to use this tool
Use Caribbean Tonnage Caller Base when you need a transparent conversion using factors already established.
How to use the tool and how it works
- Enter recordedTonnage, suppliedBaseUnitsPerTon, source. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read baseMass, source. Use the output convention below.
Multiply nonnegative recordedTonnage by positive suppliedBaseUnitsPerTon and return the nonempty source label unchanged.1
| Input field | Meaning and units | Accepted input |

| Output field | Interpretation | Returned shape |
|---|---|---|
| baseMass | Base Mass | Required. Finite number. |
| source | Source label or index interpreted under the specific calculation above. | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- The caller must select the correct historical mass convention; tonnage is not automatically interpreted as mass or vessel capacity.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Verify the original unit definition, quantity type, and measurement uncertainty before applying a conversion factor.
