Question: how much does an empty 16.9 oz water bottle weigh?
Answer: just for ease of answering we will use the US Gallon, as its volume and weight is different from that of an Imperial Gallon…. then multiply by 16.9 to get your answer. Your answer should be 17.58 ounces in weight per 16.9 ounces liquid or 1 pound and 1.58 ounces.
