Conversions are numerical references. Apply the units and design conventions required by your project.

Engineering assumptions

Use conversion values with project context.

Numerical conversion only

The converter changes units and common engineering quantities. It does not check whether a value is appropriate for a design case.

Weld size reference

The fillet weld relation uses the geometric throat-to-leg relationship shown in the card. Confirm the governing weld design rules for final checks.

Precision

Displayed precision can be adjusted for readability. Keep adequate significant figures in calculations where rounding affects results.
