Our Editorial Policy

Every converter on CanvaTools is built and reviewed by our engineering team before publication. We take data accuracy and user trust very seriously.

International Standards

We follow strict international standards and definitions set by recognized authorities:

• International Bureau of Weights and Measures (BIPM)
• ISO 80000-3: Quantities and units — Part 3: Space and time
• NIST (National Institute of Standards and Technology)

Our Review Process (YMYL Standard)

For topics concerning Your Money or Your Life (YMYL) such as health, medicine, and finance, we adhere to strict E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) guidelines. We never publish a tool until it has successfully passed our multi-step quality assurance process:

1. Built by Qualified Engineers: Every formula is programmed and vetted by our technical staff for precision and performance.
2. Subject-Matter Expert Review: Medical calculators (e.g., BMI, BMR, Medicine Dosage) are reviewed by board-certified physicians, and financial tools (e.g., Mortgage, ROI) are audited by certified financial planners (CFA/CFP).
3. Reviewed against Official Definitions: We ensure all constants and conversion ratios match official SI definitions or current medical/financial consensus.
4. Continuous Auditing: Formulas and tax brackets are updated regularly to reflect the latest scientific literature and federal laws.
