A few useful things to know
Which gallons and ounces are used?
Volume uses US liquid gallons and US fluid ounces, not Imperial measures. Weight uses ordinary avoirdupois ounces and pounds, not troy ounces.
Are results exact?
Conversions use standard factors and results are rounded to at most 10 significant digits. This tool is for everyday use, not precision laboratory work.
