how much does 5 gallon of water weigh ?

Answer 1

1 gallon of water = 3.78541178 litre
5 gallon of water = 18.9270589 litre

1 litre of water has an index mass of ~1.000

Thus,

1litre of water = 1.000kg

18.9270589 litre of water = 18.9270589 kg

5 gallon of water = 18.9270589 kg

Or in pounds,

= 18.9270589 x 2.20462

= 41.726972592118 pounds

Hope that helps!!

Answer 2

There is a saying that "A pint's a pound the world around." There are 2 pints in a quart and 4 quarts in a gallon (check the supermarket dairy shelves). Therefore, a gallon of water weighs 8 pounds and 5 gallons weigh forty pounds. To lose one pound by weight reduction, you must lose a pint (or pound) of flesh or excess liquids. Losing forty pounds is like losing 5 gallons of flesh!

Answer 3

Water weighs 8 pounds per gallon. 5 gallons would weigh 40 pounds.

Answer 4

It's hard to believe all the short and incorrect answers (water is NOT 8 pounds per gallon!) or all the long roundabout answers taking us through metric equivalents and back or starting with ounces. This simple answer is, it depends. Water is not usually just water. Slat deposits and minerals can affect its density and so can the temperature and even the air pressure. So 40 degree well water in a mountain cabin could be different than 80 degree municipal water at sea level. But the best scientific and educational sources, standardizing as much as possible, sill still give numbers from 8.309104 to 8.345404 pounds per gallon for pure distilled water. By the way, sea water is about 1.025 times heavier.
Now let's assume that it's not a life or death situation and you just wonder if you'll be able to lift a pail or two. The most commonly taught 'rough' weight of water is 8.33 pounds per gallons. (Lazy people use 8.4)
So 8.33 * 5 = 41.65 pounds (plus any container it's in) if it’s clean, relatively pure water at somewhere near room temperature and not on a mountain or in the eye of a hurricane.

Answer 5

Units are such that one liquid ounce of water weighs one ounce-weight. 16 ounces in a pound.

An American gallon is 4 quarts of 32 ounces each = 4 times 2 pounds = 8 pounds. 5 US gallons weighs 40 pounds (plus the weight of the container, I guess)

An imperial gallon is 4 quarts of 40 ounces each (4*2.5 = 10 pounds); 5 Imperial gallons = 50 pounds.

Answer 6

A pint of water weighs 1.3lb. A gallon weighs 10.4lb. 5 gallons weigh 41.6lbs

Answer 7

1 Gallon is roughly 4.5l of water (British.Standards)
1l of water weighs 1kg,
so 5 Gallons x 4,5 = 22,5l of water which weighs roughly 22,5kg.
If you using American Standards then multiply by 3,5 to get the ammount of litres.

Answer 8

I loved to play ball, and for the first time in my life, I'm actually useful, at a ballgame, instead of just a big stationary person, that maybe if the ball comes within this range, I might get it. I was wearing-I'd always wore XX kind of jersey. And then I went down to medium. And then the medium was too big, that it's coming down here.

So I'm wearing a rockin' outfit, and I'm making a play, and the guy stops, beans it in the face 'cause he says, "Look at your body. You're rockin' hard." And that was the first time I had ever gotten a compliment like that in my whole life.

Answer 9

if you want the exact weight then you should have given the atmospheric conditions.

assuming @STP, density water= 1000 kg/m3

since 3.78 li = 1 gallon, density is mass over volume

by dimensional analysis,
mass=density x volume

mass therefore = (1000 kg x 3.78 x 5)/1000 li/1 m3
mass in kg = 18.9 kg

mass in lbs = 18.9 kg x 2.2 lb/1 kg
= 41.58 lbs

if you want exact weight, refer to my good friend robert perry he has a book called Perrys chemical engineers handbook youd be able to find the actual density of water at any given atmospheric condition ( temp.)

You need to exercise.. if your not overweight.. if your underweight as you say.. then your muscle need to be toned. and the only way to tone your muscles is exercise. try something like yoga or pilates, or speed walking.
As for eating. I dont' know what you are eating now. but stick to healthy things and avoid foods that will just add fat to your body..
