Description
Return labeled strength on a supplied numerator/denominator basis.
A medicine label expresses an amount on a particular mass, volume or other quantity basis. Ratios are meaningful only when numerator, denominator and active-component conventions match; a supplied conversion or fraction does not establish medicine equivalence or an appropriate dose.
Return labeled strength on a supplied numerator/denominator basis.
When to use this tool
Use Medicine Label Strength Unit Pair when checking the stated medicine-label amount, unit or component-basis convention.
How to use the tool and how it works
- Enter amount, numeratorUnit, denominator, denominatorUnit. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read strength, unitPair. Use the output convention below.
Return labeled strength on a supplied numerator/denominator basis. Require amount >= 0, denominator > 0 and nonempty unit labels; strength = amount/denominator, unitPair serializes both labels.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| amount | Amount | Required. Finite number; minimum 0. |
| numeratorUnit | Numerator Unit | Required. Text; maximum UTF-16 length 8192. |
| denominator | Denominator | Required. Finite number; strictly above 0. |
| denominatorUnit | Denominator Unit | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| strength | Numerical amount per denominator; units are the serialized numeratorUnit/denominatorUnit pair. | Required. Finite number. |
| unitPair | Unit Pair | Required. Text; maximum UTF-16 length 8192. |

}Limitations and assumptions
- Labels are not converted or cross-validated; this is not a recommended dose, route or safe medicine instruction.
- 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 label, ingredient identity and source edition with a qualified pharmacist; use verified unit conversion and clinical assessment for any actual medicine decision.
