Last updated: October 9, 2026
By using mmintoinches.com (“the Website”), you agree to these Terms of Service. If you do not agree, please do not use the Website.
Permitted Use
You may use the calculators, conversion pages, charts and printable PDFs free of charge for personal, educational and professional work, including in workshops, engineering, manufacturing and trade settings.
You may print the charts and PDFs for your own use or for use within your workplace.
You may not:
- Republish, resell or redistribute the Website’s content, charts or PDFs as your own, or offer them for download elsewhere
- Copy the Website’s text or design into another website or product
- Attempt to reverse-engineer, disrupt or overload the Website
- Remove copyright or attribution notices
Linking to any page of the Website is welcome.
Accuracy of Results
We work to keep every result correct, but you should check critical measurements against the drawing, specification or the part itself.
- Inch results are generally shown to 4 decimal places.
- Millimeter results are generally shown to 2 decimal places.
- Fraction results are approximate. The calculator rounds to the nearest 1/64 inch, and the conversion pages also show the nearest 1/16 inch. Where a fraction is approximate, the page shows how far it is from your original value.
- One inch is exactly 25.4 mm, so conversions are exact before rounding; any difference comes from the rounding shown.
- Nominal product sizes (for example pipe sizes or sheet thicknesses) can differ from actual measured sizes.

To the extent permitted by law, mmintoinches.com and its owner are not liable for any loss or damage arising from use of, or inability to use, the Website, including loss resulting from reliance on a conversion result. Use of the Website is at your own risk.
