Its counterpart in weight measuring units is the pounds.

A US liquid gallon would weigh an average of 8.34 pounds.

The same US liquid gallon holds an equivalent of 3.875 liters of liquid. For the imperial gallon holds more litres at 4.55 liters. That means the US gallon and the Imperial gallon are not of the same capacity.

If one gallon is 8.34 pounds how heavy would be 5 gallons of the same liquid?

This is simple mathematics whereby you multiply 5 gallons with 8.34 pounds to get 41.7 pounds.

So, 5 US gallon of liquid would weigh 41.7 lbs.

Lets see what the imperial measurements would be.The British imperial gallon has a weight of 10.022 pounds.

Confusing? Remember there is British Imperial measurements and the imperial measurements.

So now if British imperial gallon is 10.022 pounds then 5 British imperial gallon would be 50.11 pounds. All this measurements are on average since there are factors which affect the weight of liquids.

The US 1 gallon of water weighs 8.34 lbs or 3.78 kg.

An imperial gallon (UK) weighs 10.022 lbs or 4.546 kg.

Other helpful figures.

1 gallon is approx 3.75 liters.

1 liter i

1 kg is about 2.2 lbs

so, 3.75 kg is about 8.25 lbs and 1 gallon is about 8.25 lbs

5 gallons = 18.75 litres = 18.75 kg = 41.25 lbs
