Conversion Methodology

ConverterBase uses stable unit definitions and fixed conventional factors. The calculators are generated from one reviewed unit table so each page, chart, search result, and alternate-unit answer uses the same math.

Sources

Primary references are NIST SI units, NIST U.S. customary-to-metric relationships, and the BIPM SI overview. Category pages link to the reference used for that family of units.

• NIST SI Units
• NIST approximate conversions between U.S. customary and metric measures
• BIPM measurement units

Exactness and rounding

Internal calculations keep more precision than the displayed result. Displayed numbers are shortened for readability, and formulas show the practical relationship used by the calculator.

What is excluded

ConverterBase avoids exchange rates, energy prices, and other values that require manual freshness claims. If a calculator needs live data, it is not included as a static conversion page.

Corrections

If a factor, label, or use-case note looks wrong, send the page URL and correction to [email protected].
