How heavy is a 55-gallon drum of water

The dark blue color of this barrel restricts light and helps control growth of harmful algae and bacteria

Store your barrel out of direct sunlight and off the direct ground. 

Regularly rotating your water helps flush out any accidental contamination. 

For outdoor storage, keep on NE corner of  home to reduce exposure to sunlight.

Be sure to protect barrel from freezing temperatures, or leave 9 inches of headspace to allow for expansion.

Each 55-gallon barrel provides enough water for drinking, cooking, and light personal sanitation for 4 people.

The weights of empty 55-gallon drums vary depending on material and dimensions. Metal empty 55-gallon drums weigh approximately 40 pounds, whereas plastic 55-gallon drums weigh half as much.

There is no uniform weight to a 55-gallon drum; weight depends on the dimensions and materials of the drum. A 55-gallon plastic drum weighs approximately 20 pounds. For example, Granite Environmental’s 55-gallon closed-head drums weigh 22.2 pounds each. Closed steel drums built by the Lexington Container Company that are each 23 inches in diameter weigh 34 to 38 pounds. The same company’s unlined 55-gallon drums with a 24-inch diameter weigh 44 pounds each.

Let's do this.

we know that 1 Gallon = 3785 ml

we know that 1 ml of water = 1g (metric system is awesome)

so 1 gallon of water = 3785 grams

1 lb = 453 grams

1 gallon of water = ( 3785 / 453 ) lbs

about 8.35 lbs / gallon

* 55

459.25

Water is so important for everyone; it is recommended that we should drink at least 2 liters every day to keep us fit and healthy.

I have never used water from my faucet for drinking because, although it looks clear and clean, I’m a little paranoid as to what invisible chemicals or bacteria it may contain.

Consequently, I always buy water from the local store, and I always carry a bottle of water with me at all times, wherever I am. I normally buy 55 gallons with my weekly shop, but it’s heavy!

So, how much do 55 gallons of water weigh?

55 gallons of water weighs 458.96 pounds, or 208.18 kilograms.

To find the total weight we only need to multiply the 55 gallons by the weight of a gallon – which is 8.34 pounds at 62°F.

Different measures of gallons

If you’re wondering why I actually specified a U.S. gallon in my answer I have done so, as there are actually three different measures of a gallon.

The US uses two different gallon measures; the liquid gallon that we have used in the calculation above and is the measure that is commonly used.

There is also, however, a dry gallon. The dry gallon is a historic measure that originated from the British dry measure that quantified the volume of 8 pounds of wheat.

Using the dry gallon as a measure a gallon of water would weigh approximately 9.71 pounds which would mean that using the dry measure 55 gallons of water would weigh 534 pounds.

There is also the UK or Imperial gallon measure that quantifies a gallon of water as weighing 10.02 pounds which would give a figure of 551 pounds for the weight of 55 gallons of water.

Using the different gallon measures results in a different range of weights:

  • US Liquid gallon 459
  • US Dry gallon 534
  • UK gallon 551

Therefore, it is important when looking at the weight of 55 gallons to ask the question “What gallon measure are we going to use?” especially if we are paying for a liquid by the gallon or if we are adding something to the water to create a plant fertilizer or weed killer where the relationship of quantities is important.

As with a cooking recipe, the correct quantities of the ingredients of plant fertilizers are incredibly important.

How do we know what a gallon of water weighs?

The gallon is a measurement of volume, it is, therefore, necessary to convert the volume measurement to one of weight, which in the case in question is pounds.

It would be an easy task to put a gallon of water on to a set of scales and measure the weight, but all measurements have already been quantified as part of a standardized system of weight and measures.

We are fortunate in today’s age that it doesn’t take too long to find detailed information regarding measures, and how these can be converted.

When the conversion of the 55 gallons to pounds is done, it easy to look up the figure that shows how much a pound of water weighs, although for those for whom the devil is in the detail there are formulas for converting everything.

Will temperature affect the weight of 55 gallons of water?

Yes, the temperature of water has an unusual effect on the properties of water.

The density of warm water is lower than that of cold water, especially when it is just above the freezing point of water.

This property is known as the anomalous expansion, and it actually prevents fish in rivers from dying since the water just below the ice being slightly less dense and warmer prevents it from freezing.

This effect is caused by hydrogen bonding and does result in the weight of warm water being slightly less than that of cold water.

Temperature does affect the weight of water; however, the difference is slight and not sufficiently large enough to generate any significant difference in the value.

Does the elevation of my house affect the weight of water?

Since weight is a property that is related to a specific mass within a gravitational field the greater the distance a mass travels from the source of the field the less effect the field has on the mass.

The reduction would continue as the distance increases until the mass, although still the same will weigh nothing.

Apparently, the distances that water can be taken to a higher elevation on earth does show a reduction in weight that can be measured, however not necessarily felt.

I wonder if this is true since every week, I visit the store to buy 55 gallons of drinking water in gallon containers. This task calls for the water to be handled and moved a lot of times.

  1. Load it into my trolley from the shelf
  2. Unload it at the checkout
  3. Load it back into the trolley
  4. Transfer it into my car to drive to my mountain home
  5. Unload it from my car and carry into my utility room

How much, then does 55 gallons of water weigh?

We can appreciate that to answer the question of how much 55 gallons of water weighs involves a simple calculation using some extremely basic math.

The first task is to be sure which gallon measure we are using, we then need to realize that since a gallon is a measure of volume, we need to convert the volume measure to a measure of weight. The measurement of weight in this case is the pound.

Once we have established exactly how much a gallon weighs in pounds, it is a simple task to calculate the weight of 55 gallons by multiplying the gallon weight by the number of gallons.

The weight of a gallon of water is quantified using pure water at a certain temperature.

Even though the weight of water is affected by temperature, and altitude, the difference in weight to the standardized measurement, although large enough to be measured does not create any major difference to the actual value.

55 gallons of water weigh 458.7 pounds, or 208.06 kilograms.

How heavy is a 55-gallon drum of water

Three years ago, I bought an off-grid Cortijo in a small valley in the Andalucian mountains. Although, perhaps the lifestyle is in my genes as my grandfather and his four brothers were Homesteaders in Alberta Canada in the 1900s.

The mountains of Spain are a difficult place to grow many of the flowers that I was used to in the UK. However, veggies grow well year-round. Peppers, tomatoes, potatoes, lettuce, cucumber, melons and chard all fare well in the Mediterranean climate. Almond trees provide me with a cash crop of around 1 ton while still retaining some to make almond milk and flour.

How heavy is a 55 gallon drum of oil?

A 55-gallon drum of oil weighs about 436 pounds, or close to 200 kilograms. This includes the weight of the oil drum itself. A gallon of oil weighs around 7.2 pounds, and an empty 55-gallon drum weighs around 40 pounds, including the lid.
