Terms of Use

By accessing or using Units Converter ("the Service"), you agree to these Terms of Use. If you do not agree, please stop using the Service. These Terms form a binding agreement between you and the operator of Units Converter. We may update them from time to time; the date at the top reflects the current version.

Units Converter is provided free of charge for personal, educational, and commercial use, subject to the following conditions:

• You may use the Service for any lawful purpose, including commercial work.
• You may cite Units Converter in academic and journalistic publications. A link back to the relevant page is appreciated but not required.
• You may not scrape the entire site, mirror it without permission, or republish substantial portions of the encyclopedia content as if it were your own.
• Automated bulk requests must respect robots.txt and rate limits. Bots that abuse the service may be IP-blocked.
• You may not use the Service to develop a competing product by training machine-learning models on our content without express written permission.

Units Converter takes scientific accuracy seriously. Every conversion factor is sourced from primary references (NIST, BIPM, IEEE, IUPAC) and verified to 8 significant figures. We document our methodology and welcome corrections.

However, the Service is provided "as is" without warranty of any kind. While we strive for perfection, we cannot guarantee that every conversion is free of errors caused by software bugs, transcription mistakes, or unexpected edge cases. You are solely responsible for verifying critical conversions before relying on them in life-safety, structural-engineering, medical, aviation, financial, or legal contexts.

For high-stakes work, always consult the primary source publication (e.g., NIST SP 811, BIPM SI Brochure) directly. Units Converter is a teaching and reference tool, not a substitute for professional judgment.

The Units Converter brand, logo, design, and original written content are protected by copyright and trademark. The numerical conversion factors themselves are public-domain scientific facts and are not subject to copyright; you are free to use them in any way.

Unit definitions, descriptions, and overviews on this site are original to Units Converter unless explicitly attributed otherwise. You may quote brief excerpts (under 200 words) for educational and journalistic purposes with attribution. For longer reproductions or translations, please contact us for permission.

To the maximum extent permitted by applicable law, Units Converter, its operators, and its contributors shall not be liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of the Service — including but not limited to errors in conversion results, service unavailability, or data loss. Some jurisdictions do not permit the exclusion of certain warranties; in those jurisdictions, our liability is limited to the maximum extent permitted by law.

Units Converter occasionally links to external websites such as NIST, BIPM, and educational institutions. We do not control these websites and are not responsible for their content, availability, accuracy, or privacy practices. External links are provided as references for further reading; clicking them is at your own discretion.

We reserve the right to suspend or terminate access to the Service for any user who violates these Terms, attempts to disrupt the service, or engages in unlawful activity. We also reserve the right to modify, suspend, or discontinue any part of the Service with reasonable notice.

These Terms are governed by the laws applicable at the place of operation of the Service, without regard to conflict-of-law principles. Disputes arising from these Terms or your use of the Service shall be subject to the exclusive jurisdiction of the courts in that jurisdiction.
