Ankle-brachial index (ABI): a painless exam that compares the blood pressure in your feet to the blood pressure in your arms to determine how well your blood is flowing. This inexpensive test takes only a few minutes and can be performed by your healthcare professional as part of a routine exam.
1 US gal of pure water weighs anywhere from 128.0 oz (for water very close to boiling) to 133.3 oz (for cool room temperature and cold water).
One US Gal=128 fluid oz...not to be confused with avd oz used in weight, of which 16 make up a pound (not to be confused with the Brittish pound sterling). One cup here is generally 8oz, so one gallon yields 16 cups...unless you mean coffee-cups which usually are 6oz, giving a very odd number of cups per gallon.
