Calculate how much water weighs given a certain volume with the assistance of this free online water weight calculator.

How Much Does Water Weigh?

You can determine the weight of the water by taking into account its density. The density of water at room temperature is about 1 kilogram per litre (kg/L) at 39.2°C or 0.99802 g/ml at 21°C. If you know the density and volume of the water, then you can calculate the mass of the water with the help of the following formula:

Density = Mass/Volume
or
Mass = Density * Volume

Effect of Temperature and Density on Water Weight:

The weight of the wt water varies directly with the changing temperature. At high temperature, water weighs less because it becomes less dense. This is because the quantity of the oxygen in the water decreases due to chemical reactions taking place at higher temperatures. Due to this lack of oxygen gas, the weight is reduced enough.

On the other hand, at low temperature, the quantity of dissolved oxygen increases enough. Due to this excess of oxygen, the density of the water will become higher enough which makes it weigh more.

For this reason, the weight of the water changes every time as the temperature is not always static. This is why it is very difficult to measure the mass every single minute. But do not worry at all as our best water weight calculator will instantly determine the weight. All you need to do is to fetch the temperature and you will get to know how much specific quantity of the water weighs that you are having.

Below here we have arranged a table that contains the density of water at different temperatures:

How Much Does A Gallon of Water Weigh?

According to the US metric system, a normal standard sized gallon of water contains about 8.34 pounds of water. No doubt that increasing the number of gallons will also increase the mass of the water. Let us have a look of specific number of gallons that contain certain mass of water that could be determined by the assistance of our best water weight calculator and are as follows:

Number of Gallons  Water weight in pounds
6 50.04
2.5 20.85
8 66.72
125 1042.5
3 25.02
1000 8340

Key Points For Calculating Water Weight:

If you are interested in determining the mass o the water, you need to keep following steps to do so:

  • Convert the given volume of water in liters
  • Then convert the density of the water as kg/L
  • After that, put the values in the following formula:

Mass = Density * Volume

The free online water weight calculator also makes use of this formula to convert the water volume to weight.

How To Calculate Water Weight?

Let us go for calculating the mass of water in the following examples:

Example # 01:
How much does a liter of water weigh at a temperature of 10 degree celsius?

Solution:

Here we have:

Density of water at 10°C is 0.99975 g/cm3. So we have:

Mass = Density * Volume
Mass = 0.99975 * 1
Mass = 0.99975 kg

Example # 02:

How much does 275 gallons of water weigh?

Solution:

As we know that one single gallon of water weighs about 2.21 pounds, so we have:

275 gallons = 275 * 2.21
275 gallons = 607.75kg

Here our free calculator also displays weight conversions in different other units as well.

FAQ’s:

How heavy does one cup of water weigh?

One cup of water contains about 236 grams or 0.520 282 186 95 Pounds that you could also check with the assistance of our best water weight calculator.

Does ice and water weigh same?

No, not at all! If you take the same volume of water and ice in a different but same container, water will weigh more. The reason is that the density of the ice is less than the water. When density is low, it will also weigh less. That is why ice floats on the surface of water.

Is water heavier than snow?

Basically, snow is water. So the more the snow, the more the amount of water is. This snow weighs about 7 pounds per cubic feet. If snow is more wet, then the amount of water is about 20 pounds per cubic feet.
