LazyTools works hard on accuracy — unit conversions use the exact, internationally defined factors, and formulas are shown on every page so you can check the math. Still:

• Informational use. Tool outputs are provided for general information. They are not professional, legal, financial, medical or engineering advice.
• Verify critical results. If a result feeds a decision with real consequences — a medication dose, a structural spec, a financial commitment — verify it against an authoritative source or professional.
• Approximations are labeled. Where a conversion is inherently approximate (average month lengths, Mach at sea level), the page says so explicitly.
