Editorial Policy

The Units Made Easy editorial team consists of software engineers and technical writers with combined backgrounds in scientific computing, applied metrology, and educational content. Every converter, calculation, and reference article on this site is reviewed by at least one editor before publication and periodically re-audited to reflect the latest international standards.

Every conversion factor on Units Made Easy derives from one of the following authoritative sources:

• BIPM (International Bureau of Weights and Measures) — the definitive body for the International System of Units (SI).
• NIST (National Institute of Standards and Technology) — the U.S. authority on measurement and calibration.
• ISO 80000 (Quantities and Units) — international standards for units and quantity notation.
• International Yard and Pound Agreement (1959) — defines 1 inch = 2.54 cm exactly and 1 lb = 0.45359237 kg.
• ITS-90 (International Temperature Scale of 1990) — for temperature conversions.
• OECD and WHO datasets — for population statistics, average heights, and demographic references.

1. Source lookup: Each conversion factor is cross-referenced against at least two primary standards documents.
2. Precision review: Values are computed at full double-precision floating-point accuracy; displayed values are rounded to four to six significant figures for readability.
3. Unit tests: Every calculator is unit-tested against reference values published by BIPM/NIST before deployment.
4. Content review: Every published page is read by at least one editor for clarity, accuracy, and consistency.
5. Periodic audits: All content is re-audited quarterly and updated when standards change.

Accuracy is non-negotiable. If you find a conversion factor, formula, or fact on this site that is incorrect, please contact us. We commit to:

• Investigating every reported error within 24 hours.
• Correcting factual errors within 48 hours of confirmation.
• Documenting significant corrections on the affected page with a “Correction” note and date.
• Never silently editing pages when factual accuracy is at issue.
