Description
Convert a recorded voiding-event volume between millilitres and litres.
Urinary records distinguish collected volume, collection duration, mean flow, anatomical side and the source of symptom codes. Millilitres, litres and cubic millimetres are volume units; dividing volume by a specified interval gives a mean rate. A diary transcription or volume balance needs verified collection and clinical context before it can inform care.
Convert a recorded voiding-event volume between millilitres and litres.
When to use this tool
Use Voiding Event Volume Unit when you already have volume, inputUnit and need to convert a recorded voiding-event volume between millilitres and litres.
How to use the tool and how it works
- Enter volume, inputUnit. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read milliliters, liters. Use the output convention below.
Require volume>=0 and inputUnit mL or L; multiply litres by 1000 for mL and divide mL by 1000 for L.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| volume | Volume | Required. Finite number; minimum 0. |
| inputUnit | Input Unit | Required. Text; one of "mL", "L"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| milliliters | Milliliters | Required. Finite number. |
| liters | Liters | Required. Finite number. |

}Limitations and assumptions
- Volume is supplied; no collection completeness, bladder function or clinical threshold is assessed.
- 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
Review the original collection log, measurement units and instrument protocol before interpreting a volume or flow. Use the full recorded trace for peak or time-varying flow; a mean or transcription is only one component of that record.
