SI Converter Info/Help

This information has been developed by Lou Gervais. Many publications and resources have been used to develop this conversion tool. All attempts have been made to ensure the most complete and accurate information available but is provided as is without limitations or implied warranty.

This tool handles more than 830 different conversions of various SI units of measurements that include length, weight, volume, temperature and the conversion of Binary, Decimal, Hex and Octal with full support of fractional numbers. It also supports both positive and negative numbers from the user with selecTABLE range of precision from 1 to 32 digits except for the Binary-Decimal-Hex-and Octal functions.

SI units and standard abbreviations have been used both to save space and support international standards. Please be advised that as of this release the internal functions of JavaScript are still limited to 16 digits of precision. This conversion tool may be updated from time to time to add additional conversion units or updates.
