How Much Does 10 Liters Of Water Weigh? (Answered!)

What Is The Weight Of 10 Litre Water?

The water’s weight can seem a mystery for many, judging by its inability to maintain a particular shape. When it comes to weight, we are most conversant with the weight of solid objects that have a fixed mass and pay less attention to liquid and gaseous substances.

Some people think that other forms of matter, like liquid and gaseous states, do not have weight. If you also believe this, it is high time you got a new narrative. You can find the weight of every form of matter, be it solid, liquid, or gas. However, there are different methods to arrive at a result.

For this context, we will focus on the weight of water. Water is liquid, and its weight is dependent on different factors. However, the weight of water solely depends on one thing; volume. Since liquids are measured in volume, it is possible to calculate their weight from their volume.

How much do 10 liters of water weigh? Without any external influence, 10 liters of water will weigh 10 kilograms. However, some factors might affect this value and make it weigh less or more. Just expect the weight to revolve around the value mentioned above.


Knowing the various factors affecting water weight is safer to arrive at specific figures. Knowledge of these lapses will let you make better decisions and more accurate calculations.

Factors affecting the weight of water

The weight of water depends on three main factors. The first factor is the sole factor that the weight of water depends on, while the other two have minimal effect on its net weight. Let’s have a look at some of these factors and how they affect the weight of water.

The first factor affecting the weight of water is volume. When making calculations involving the weight of water, you MUST put the volume of the water as the fundamental parameter. Remember I mentioned that liquids and gases are measured in volume since they don’t have specific shapes?

After knowing the volume of water, it is easy to convert it to weight because the volume of water directly impacts its weight. The greater the volume, the greater the weight of the water. However, a fixed formula is used to convert water volume to weight.

The second factor that affects the weight of water is temperature. Although the temperature has a minimal effect on the net weight of water, it is still essential to consider it to avoid errors. There is a simple principle on how temperature relates to the weight of water.


As the temperature of water increases, the weight decreases. Sometimes, people say the temperature is inversely proportional to its weight or density. Let me put this in context. The warmer the water, the lower the weight, and vice versa.

For example, I get two water samples with equal volumes; I freeze one and heat the other. When you calculate the weights of both samples, you will find that the cold water weighs more than the hot water. It is as simple as that. Essentially, 1 liter of cold water will weigh more than 1 liter of hot water.

However, the weight difference might be very small since the temperature has little effect on its weight. If you weigh 1 liter of cold water as 1.1kg, 1 liter of hot water might weigh around 0.9kg. The discrepancy might be less or more than what is even stated above. It just depends on how hot or how cold it is.

Lastly, another factor that affects the weight of water is salinity. Unlike temperature, salinity has a lesser effect on the weight of water. Nevertheless, we should still consider it when trying to find out the weight of water.

The weight of water increases as its salinity increases. For example, if you get 10 liters of ocean water and 10 liters of fresh water for weight measurement, the former will weigh more than the latter. Since the salt will dissolve in the water, it will add to its mass, increasing its net weight.

How to calculate the weight of water

The volume of water is measured in liters while its weight is measured in kilograms; this means the conversion will involve both units. 1 liter of water is equal to 1 kilogram of water. The conversion is so simple and basic that you can calculate large figures within seconds.

If 1 liter of water weighs 1 kilogram, 10 liters will weigh 10 kilograms. Also, 100 liters of water will weigh 100 kilograms. The conversion goes on and on, giving you a fundamental principle to follow when finding the weight of water in kilograms from its volume in liters.

How much do 10 liters of water weigh in lbs?

Weight is not only measured in kilograms; it is also measured in lbs. Some people might derive their results in kilograms, while others prefer to convert them to lbs. Converting the weight of water from “kilograms” to “lbs” is very easy, and all you need to do is simple multiplication.

Lbs is the unit for measuring weight in pounds. You might see it written as lbs in some places and pounds in others. Please don’t get confused when I use them interchangeably in this article.

1 liter of water weighs approximately 2.2 pounds(lbs). That means that 10 liters of water will weigh (10×2.2) about 22 pounds. The calculation is the base whenever you want to convert the water weight from kilograms to pounds.

Final Words

When calculating the weight of water, you should make it a priority to consider all the factors I have explained above. However, if there are no ways for you to obtain the needed parameters, then there are alternatives that you can use to find the weight of water.

A basic scale will do. All you have to do is pour the water into a bowl and place it on the scale. The scale will read the exact weight of the content without any error. Many scales measure weight in kilograms so you can use the conversion I explained if you need the value in pounds.
