Cranial Index Calculator
Measuredcranialbreadth/lengthindexONLY,not ancestry,personality,intelligenceor sensitivegroupclassification. Actual independently established geometry,calibration,product/rubricedition,units and applicability;not provenance,identity,grade,safe procedure or operational/compliance approval.
Description
The cranial or cephalic index expresses breadth relative to length under specified anatomical measurements.
The cranial or cephalic index expresses breadth relative to length under specified anatomical measurements.1
This calculator returns that geometric percentage without inferring ancestry, intelligence or personality.
When to use Cranial Index Calculator
Use this tool to apply the stated cranial index calculator operation with an explicit input and unit basis.
How to use Cranial Index Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualMaximumCranialBreadth, actualMaximumCranialLength and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualMaximumCranialBreadth | Maximum Cranial Breadth. Units, ordering and applicable branch are specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
| actualMaximumCranialLength | Maximum Cranial Length. Units, ordering and applicable branch are specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
Require positive measured breadth and length in the same unit. Divide breadth by length and multiply by 100; landmarks and whether the measurements concern a living head or a cranium must already be established.
index = 100 × breadth/length Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Cranial breadth as a percent of length. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.
