THE NUMBERS, EXPLAINED
How to use this calculator.
Aspect ratio is inside diameter divided by actual wire diameter, not a gauge number. This describes geometry and does not certify strength or suitability for a weave.
Start with your inputs
Enter jump-ring inside diameter (mm), actual wire diameter (mm). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Jump-ring inside diameter (mm) | 6 |
| Actual wire diameter (mm) | 1.5 |
A worked example
With the example inputs above, jump-ring aspect ratio is 4. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Jump-ring aspect ratio | 4 |
| Outside diameter (mm) | 9 |
How this is calculated
Jump-ring aspect ratio
Divide clear inside diameter by wire diameter.
Outside diameter (mm)
Add a wire diameter on both sides of the inside diameter.
Symbols and units
- a
- Jump-ring inside diameter (mm)
- b
- Actual wire diameter (mm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Aspect ratio is inside diameter divided by actual wire diameter, not a gauge number. This describes geometry and does not certify strength or suitability for a weave.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Jump-ring aspect ratio; Outside diameter (mm). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Aspect ratio is inside diameter divided by actual wire diameter, not a gauge number. This describes geometry and does not certify strength or suitability for a weave.
Are my inputs stored or sent to AI?
