ding dong here.... i'm trying to ensure that i get enough water & that i accurately count it throughout the day. i've got a bottle of spring water, which i'll guzzle and then re-fill from the water cooler throughout the day.

the weight on the bottle says "1 pt, .9 fl oz". does this mean that this bottle contains a pint of water??? and what is with the .9 fluid ounces? i DO know how much an ounce is, and this ain't .9 ounces.

can someone please help my poor math-addled brain out?
