Is the weight of a 1-litre of water in a plastic bottle = to 1 kg?

How much does water weigh?

The weight of water varies depending upon the temperature at which it is being stored. To give a simple explanation, hotter water weighs less, and colder water weighs more (because it's more dense). In order to accurately convert a volume of water to a weight, a density figure is therefore required.

At room temperature (70°F / 21°C), the density of water is 0.99802 g/ml. This means that for a US gallon of water at room temperature, the weight would be around 8.33 pounds. How much does a gallon of water weigh?

Effects of Water Temperature on Weight

Temperature is a key factor to dictate the weight of water in a specified volume. We all know that temperature is actually the measure of energy that water molecules possess.

Thus when temperature increases the molecules start vibrating with higher energy, pushing their neighbor on side. This results in lesser molecules in a specific volume; which is in turn density of that solution.

Keeping this in view we know

  • Warm water will have lesser molecules in specific volume
  • Cold water will have more molecules in specific volume

Gallon is nothing but a specific volume. So a gallon filled with warm water, thus containing lesser molecules of water, will weigh less. In contrast, a gallon filled with cold water will weigh more. For example, a gallon of water weighs about 8.34 at 17 degree centigrade while at 1000 degree centigrade it weighs around 8.05.

Hence, a gallon will weigh more when it is filled with colder fluid.

Global sales

Global bottled water sales have increased dramatically over the past several decades, reaching a valuation of around $60 billion and a volume of more than 115,000,000 cubic metres (3.0×1010 US gal) in 2006.[25] U.S. sales reached around 30 billion bottles of water in 2008, a slight drop from 2007 levels [26]

The rate of consumption more than quadrupled between 1990 and 2005.[27] Spring water and purified tap water are currently the leading global sellers. By one estimate, approximately 50 billion bottles of H2O are consumed per year in the U.S. and around 200 billion bottles globally.[28]

The Temperature Affects the Weight of Water

As we mentioned briefly above, temperature has an effect on the density of water, and thus its precise weight will vary with the temperature. As the temperature of water rises, it expands, causing it to increase in volume slightly.[1]

At a molecular level, as the temperature rises, the heat of the water molecules increases, which increases their energy. As the energy in the molecules rises, the particles within move and vibrate more, causing them to take up more space.

Thus, the warmer the water is, the more volume it will consume, and the lower its density will be. The chart below shows the density of water at various temperatures, according to the US Department of the Interior.[2]

Stay hydrated at all time with GIOTTO’s innovative and easy to use water bottle!

Some individuals find it easier to say than do to drink enough water, and these water bottles are here to assist. Having a water bottle at your desk or in your workout bag is one thing; remembering to refill it on a regular basis is quite another.

Types of bottled water

The FDA has established “Standards of Identity” for bottled water products sold in the U.S. For a product to be considered “bottled water”, it cannot contain sweeteners or chemical additives (other than flavors, extracts or essences) and must be calorie-free and sugar-free. If flavors, extracts and essences—derived from spice or fruit—are added to the water, these additions must comprise less than 1% by weight of the final product.[20]

Some of the more common types of bottled water are listed below:[21] [22]

  • Artesian water

This is water that originates from a confined aquifer that has been tapped and in which the water level stands at some height above the top of the aquifer.

  • Fluoridated

This type of water contains fluoride added within the limitations established in the FDA Code of Federal Regulations. This category includes water classified as “For Infants” or “Nursery.”

  • Groundwater

This type of water is from an underground source that is under a pressure equal to or greater than atmospheric pressure.

  • Mineral water

Mineral water contains at least 250 parts per million total dissolved solids (TDS). It comes from a source tapped at one or more bore holes or spring, and originates from a geologically and physically protected underground water source. No minerals may be added to this water.

  • Purified water

This type of water has been produced by distillation, deionization, reverse osmosis, or other suitable processes. Purified water may also be referred to as “demineralized water”. It meets the definition of “purified water” in the United States Pharmacopoeia.

  • Sparkling water

Sparkling water contains the same amount of carbon dioxide that it had at emergence from the source. The carbon dioxide may be removed and replenished after treatment.

  • Spring water

This type of water comes from an underground formation from which water flows naturally to the Earth’s surface.

  • Sterile water

This type of water meets the requirements under “sterility tests” in the United States Pharmacopoeia.

  • Well water

Well water is taken from a hole tapping, etc. This hole may be bored, drilled, or otherwise constructed in the ground. [23]

Conclusion

Converting the volume according to the local standard is sometimes necessary for us to do. People outside the U.S. are mostly familiar with the metric system. But it is always good to know the way to convert the volume following the measurement of the other popular widely accepted standards. Now you know exactly how many water bottles is a gallon, no matter where you are when asked the question. The main thing is to keep it mind to have your daily water intake.

Furthermore, we have reviewed some water bottles that you can carry around to keep yourself hydrated. After all, water consumption is a vital part of maintaining one’s health and well being.
