Convert newtons per square millimeter (N/mm²) to pounds force per square foot (lbf/ft²), reverse the direction, or convert a batch. Compare engineering stress data with explicit force-per-area definitions. This free tool runs locally after you choose to start.
- Enter your own values, or start with the visible example.
- Adjust values, one per line (up to 200), direction, significant digits (3–15) as needed.
- Choose the action button. Review the result, then copy text or download a file when available.
- Choose Clear all when finished to remove inputs and results from the interface.
Limits, without the small print.
Uses fixed Pa reference definitions and floating-point arithmetic. Up to 200 values, nonzero magnitude from 10^-100 to 10^100. Results are rounded to your chosen significant digits. Stress-unit equivalence alone does not establish material strength or design safety.
One job runs at a time. You can cancel it; jobs stop after 30 seconds. Browser and device capabilities affect performance.

A couple of useful answers.
Does newtons per square millimeter to pounds force per square foot converter upload my data?
No. This tool processes your input in a browser worker. Your text and files are not sent to an application server. The static host receives page and asset requests; see our privacy explanation.
Is this tool free for work and study?
Yes. No account, paid API, usage subscription or watermark fee is required. You remain responsible for your content rights and checking results. Hosting providers and their free tiers are separate from this open-source software.
What should I check before relying on the result?
Uses fixed Pa reference definitions and floating-point arithmetic. Up to 200 values, nonzero magnitude from 10^-100 to 10^100. Results are rounded to your chosen significant digits. Stress-unit equivalence alone does not establish material strength or design safety. Review important outputs against the source, especially financial, legal, identity, medical and research calculations.
