Length
Cross-convert pcb features, enclosure sizes, and panel specs.
Uses NIST-traceable conversion factors to move between metric and imperial instantly, keeping trace, enclosure, and shipping dimensions aligned.

Useful for quick IPC-2221 clearance/creep conversions.
Inputs
Unit
Fabrication focus
Panel sizes often mix metric (mm) and imperial (in). Cross-check here before ordering tooling.
Mechanical fit
Convert connector pitches, cable lengths, and enclosure offsets without switching CAD units.
Design notes
- When sharing drawings, include both metric and imperial to avoid miscommunication with CM partners.
- IPC-7351 land patterns list metric units—convert to mils only when your CAD library requires it.
- Inches vs mils: remember 1 in = 1000 mil; keep decimals to four places to avoid rounding surprises.
