// How this site works
UnitConvertTool.com is a free reference site for everyday and technical unit conversion. The goal is simple: give you a working converter plus enough explanation to understand the factor, the edge cases, and when you should double-check a critical value yourself.
Core pages cover length, weight, temperature, area, volume, time, speed, energy, pressure, and data storage in depth. Specialized converters remain available from the converters directory. Conversion factors follow SI definitions and publicly documented constants (for example BIPM SI Brochure and NIST conversion tables). Contact: [email protected].
Conversion basis and updates
Where a unit has an exact legal or international definition (such as 1 inch = 25.4 mm), we use that exact factor. Where historical variants exist (US vs imperial gallon, binary vs decimal data prefixes), the converter and guide text call out which convention is applied.
Content and factors are reviewed when standards references are updated or when users report an inconsistency. For engineering sign-off, medical dosing, legal metrology, or safety-critical work, verify results against the governing standard or a calibrated instrument—do not rely on a website alone.
