Description
Convert a supplied net-soak duration to fixed-length hours.
Fish records distinguish morphometric length definitions, relative image scales, annulus labels, detection times and survey-effort geometry. A supplied conversion factor need not apply across species or sizes. Local labels, ratios and nominal swept areas organize observations without identifying a fish, determining age or estimating abundance.
Convert a supplied net-soak duration to fixed-length hours.
When to use this tool
Use Fish Net Soak Time Unit when you already have duration, inputUnit and need to convert a supplied net-soak duration to fixed-length hours.
How to use the tool and how it works
- Enter duration, inputUnit. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read hours. Use the output convention below.
Require duration>=0 and inputUnit minutes, hours or days; multiply by 1/60, 1 or 24.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| duration | Duration | Required. Finite number; minimum 0. |
| inputUnit | Exactly minutes, hours or days; a day is fixed at 24 hours rather than a civil-day interval. | Required. Text; one of "minutes", "hours", "days"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| hours | Hours | Required. Finite number. |
{
"input": {
"duration": 90,
"inputUnit": "minutes"
},
"output": {
"hours": 1.5
}
}Limitations and assumptions
- A day means 24 hours, not a timezone-dependent civil day; no suitable soak duration, catch outcome or safe practice is selected.
- 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
Inspect original specimens, images, reference definitions and survey logs when verifying observations. Use a complete species-appropriate measurement or population method for age, abundance or condition questions; local scales and effort terms preserve only their stated basis.
