A gallon of water weighs 8.34 pounds, so 5 gallons of water would weigh 41.7 pounds.

If you’re like most people, you probably think that a gallon of water weighs 8.3 pounds. But did you know that the weight of a gallon of water actually varies depending on its temperature? For example, 5 gallons of water at room temperature (70°F) weighs 41.7 pounds, but 5 gallons of boiling water (212°F) only weighs 40.8 pounds!

So why does the weight of water change with temperature? It all has to do with density. When water is heated, it expands and becomes less dense.

That’s why hot air balloons stay up in the sky – because the hot air inside them is less dense than the cold air outside them. Similarly, when water cools down, it contracts and becomes more dense.
Now that we know how temperature affects the weight of water, let’s answer our original question: How many pounds does 5 gallons of water weigh?

At room temperature, 5 gallons of water would weigh approximately 41.7 pounds (or 18.9 kilograms). But if you put those same 5 gallons of water in a fridge or freezer, they would weigh slightly less – about 39 pounds (or 17.7 kilograms).
So there you have it!

The next time someone asks you how much a gallon of water weighs, don’t just give them the standard 8.3-pound answer – remember to ask them what temperature their gallon is at first!
