I built an inches to millimeters converter for manufacturing and hardware checks

I built Inches to MM as a small, fast reference tool for inch-to-millimeter work.

The site is aimed at practical measurement checks rather than a heavy calculator app:

• convert inches to millimeters directly;
• sanity-check hardware and manufacturing dimensions;
• use related reference pages for fasteners, drill bits, and tolerance grades;
• keep a shareable browser URL for quick lookups.

Main link: inches to mm converter

Useful reference pages:

• inch fastener to metric reference
• drill bit size chart
• tolerance grade chart

The goal is simple: answer the conversion fast, then help users move from a raw number to practical shop/manufacturing context.

If you work with CAD notes, fasteners, drill sizes, machining tolerances, or product dimensions, feedback is welcome.
