# How much does a case of water weigh?

I was lugging in a case of water to my office this morning and it occurred to me that I was lugging at least that amount around my body on a daily basis. How much do you think a case of water weighs? 24 - 9 oz bottles.

One ounce of water weighs one ounce. 16 ounces of water therefore is one pound. You can do the rest of the math.

13.5 pounds? I'm mathematically challenged so I just wanted to sure that answer is correct. If it is, I was carrying the equivalent of FIVE cases of water on my body everyday. YIKES!

You have the math correct.

Plus a few ounces (guessing) for all the bottles themselves. You can put a few empty bottles on the scale if you want to be precise about it, and find out how much they weigh.

You have the math correct but unfortunately the wrong thought process. There is a difference between a liquid ounce and a dry ounce. They are not interchangeable. One fluid ounce of water weighs 29.574 grams or 0.0652 pounds. 9 liquid ounces would be 0.5868 lbs and 24 9 liquid ounce bottles would be 14.0832 lbs in water weight plus a little for the actual plastic bottle weight.

Check your math, Lol. 0.0652 lbs per ounce x 16 ounces = 1.0432 or about 1 lbs. No it's not exact but it's close enough for government work.

(Don't try this with any other liquid, it only works with water.)

He stated the bottles were 9oz, not 16 oz. At 9oz, each bottle would weigh, 0.568 lb. Multiple that by the 24 bottles in a case, that would be 14.0832 lb. Where am I going wrong?

1 pound = 16 oz So 24 x 9 = 216 oz 216 divided by 16 = 13.5 pounds

I'm not a big fan of mathematics. 13.5 or 14 pounds doesn't really matter to me. Just a huge realization that I used to carry that around on my body on a daily basis. Thanks for all your input!

This is hilarious. Ya gotta love calorie counters.

You're not going wrong, you're missing the point.
