I have been researching US non-metric definitions. Handbook 130 says a US gallon is 231 cubic inches. http://ts.nist.gov/ts/htdocs/230/235/h130-03/07_IV_PackLabReg.pdf
Federal standard 376 says it is 3.785412 liters http://ts.nist.gov/ts/htdocs/200/202/fs376-b.pdf There is a small difference between the two values. Is the US gallon precisely defined in terms of cubic inches or liters? -- Terry Simpson Human Factors Consultant [EMAIL PROTECTED] www.connected-systems.com Phone: +44 7850 511794
