About ConvertProf

Last updated: May 7, 2026

Our mission

ConvertProf exists to make unit conversion and scientific calculation effortless for everyone — students, engineers, cooks, runners, translators, scientists. We build clean, fast, ad-supported but never ad-cluttered tools that load instantly on any device, work without sign-up, and give you the answer in one click.

What we cover

ConvertProf supports more than 15 conversion categories and a full scientific calculator:

Editorial standards

Every conversion factor on ConvertProf is sourced from primary references and cross-checked against at least two of the following authorities:

  • NIST Special Publication 811 (US National Institute of Standards and Technology)
  • BIPM SI Brochure (Bureau International des Poids et Mesures)
  • ISO 80000 series (Quantities and units)
  • EU Regulation 1169/2011 for nutritional energy values

Historical units (pood, verst, cubit, desyatina) follow the standardised values published in academic metrology references; we explicitly note where regional and period variation existed.

Accuracy methodology

Our conversion engine performs all internal math in double-precision IEEE-754 floating point, then displays results rounded to six significant figures. For most everyday use this matches the precision of professional engineering calculators. For mission-critical work (medication, aerospace, certified survey) we recommend cross-checking with primary sources.

Independence

ConvertProf is independently operated. We do not accept paid placements, sponsored conversions, or affiliate kickbacks within our converter results. Display advertising (Google AdSense) is clearly separated from editorial content and never influences which conversions we publish.

Our editorial guides

Beyond the converter, our blog publishes long-form guides explaining the units behind the math:

Corrections & feedback

We take accuracy seriously. If you spot an incorrect conversion factor, an unclear explanation, or a missing unit, please reach out via the FAQ page. Verified errors are corrected within 48 hours.

Privacy & terms

We don't require accounts and store no personal data on our servers. See the full Privacy Policy and Terms of Service for details.

Thanks for choosing ConvertProf. 🙂
