Description
Divide nonnegative count by positive countedFields and multiply by nonnegative targetFields.
Counts per field or area depend on the sampled denominator and any overlap or edge policy. Scaling a sampled density assumes the counted region represents the target region.
Divide nonnegative count by positive countedFields and multiply by nonnegative targetFields.
When to use this tool
Use Microscope Field Count Factor when you need a transparent field, grid, or area-normalized count.
How to use the tool and how it works
- Enter count, countedFields, targetFields. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read scaledCount. Use the output convention below.
Divide nonnegative count by positive countedFields and multiply by nonnegative targetFields.1

| countedFields | Counted Fields | Required. Safe integer; minimum 1. |
| targetFields | Target Fields | Required. Safe integer; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| scaledCount | Scaled Count | Required. Finite number. |

}Limitations and assumptions
- Scaled counts may be fractional; this assumes representative equal fields without sampling-error or biological correction.
- 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
Use the original images and a documented sampling and counting protocol, with uncertainty analysis where needed.
