Table Percentage Calculator
Observedtable/girdlediameterpercentage Actual independently established geometry,calibration,product/rubricedition,units and applicability;not provenance,identity,grade,safe procedure or operational/compliance approval.
Description
Table percentage compares the top facet's diameter with the girdle diameter under a specified measurement convention.
Table percentage compares the top facet's diameter with the girdle diameter under a specified measurement convention.1
This geometric ratio alone does not establish cut grade.
When to use Table Percentage Calculator
Use this tool to apply the stated table percentage calculator operation with an explicit input and unit basis.
How to use Table Percentage Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualTableDiameter, actualGirdleDiameter 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 |
|---|---|---|---|
| actualTableDiameter | Table diameter, on the basis specified in the algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
| actualGirdleDiameter | Girdle diameter, on the basis specified in the algorithm. | number | required; finite; strictly positive; further conditions in the algorithm |
Require nonnegative table diameter and positive girdle diameter in matching units. Divide and multiply by 100; values above 100 are retained.
table percent = 100 × table diameter/girdle diameter Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Observed table/girdle percentage. | 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 successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Star Facet Length Percentage Calculator. Star-facet percentage describes a projected facet length relative to a separately defined table-to-girdle radial reference.
For a related operation, use Lower Half Facet Percentage Calculator. Lower-half percentage compares a projected facet length with a defined girdle-to-culet reference.
