How much does a 5 gallon bottle of water weigh?..
This question needs to be split into TWO questions and the answer relates ONLY to the weight of the water. The weight of the container needs to be added (1 kg for the one I use):
How much does a 5 US gallon bottle of water weigh? = 18.93 Kg
18.93 kg = 41 lb 11.736 oz
How much does a 5 UK gallon bottle of water weigh? – 22.73 kg
22.73 kg = 50lb 1.7772 oz
5 US Gallons = 18.9271 Litres
5 UK Gallons = 22.7305 Litres
One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. (1.000028 kg to be exact)
1 kg = 2 lb 3.2740 oz
Weight of 5 US Gallon Water Container:
Plastic: 1 kg for this 5 US gallon Blue water container example.
Total weight Container with water: 19.9 kg. (19.9 kg = 43 lb 13.952 oz)
