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).
To calculate how many 16.9 oz bottles equals a gallon you need to know how many ounces are in a gallon. There is 128 oz. in a gallon. If each water bottle contains 16.9 oz. of water, then it would take 7.57 water bottles to reach a gallon. Obviously we cannot have .57 of a water bottle so we would have to round up to 8.
