Description
Divide nonnegative ribThickness by positive wallThickness for ratio.
Ideal product geometry maps dimensions into lengths, areas, or coordinates under a stated shape model. A dimension ratio does not by itself establish manufacturability, strength, or usability.
Divide nonnegative ribThickness by positive wallThickness for ratio.
When to use this tool
Use Rib Thickness Nominal Wall Ratio when you need one explicit product-geometry component.
How to use the tool and how it works
- Enter ribThickness, wallThickness. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read ratio. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| ribThickness | Rib Thickness | Required. Finite number; minimum 0. |
| wallThickness | Wall Thickness | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| ratio | Ratio using the numerator and denominator conventions stated above. | Required. Finite number. |

}Limitations and assumptions
- Matching length units are required; no moldability, sink-mark, structural, or material-specific acceptance guideline is supplied.
- 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.
