# How to easily get the density of water – easy hack

# How actual can I get the density of water

How to calculate the density of water? The first thing which you need to understand is the definition of density at all. As simply as possible, the density is just the water mass per the water volume. So based on it, to calculate the density of water, you should divide the value of the mass by the value of the volume. That’s all, then you will get your result. You probably know it, but to make it clear – if you want to get the result in lb/ft3 you need to calculate the mass in pounds and volume in cubic feet. Remember – if the numbers will be difficult to calculate on your own, you can always use a calculator.

## You have to define density of water

How does the density of water lb/ft3 look? To answer this question you firstly need to know the definition of the density of water at all. So how does it look? It is just the mass of a substance per unit volume of this substance. So to sum up, it shows the topic in a descriptive way. There is no legal definition. But let’s focus on the water density lb/ft3. Thanks to the general definition we know that the water density lb/ft3 is the mass determined in lbs per volume given in cubic feet.

## Density main factors what you should to know

The value of the density of water lb/ft3 may change depending on a few conditions, like the temperature or the salinity, but it is possible to define the basic value. What is it exactly? The basic value is defined as a value in neutral conditions (freshwater at 4 degrees Celsius) and it is equal to 62.4 lb/ft3. Did you expect such a huge number? Regardless of whether your type was close to the answer or not, one thing is obvious. If you know the basic value, you will learn easily also about other values of density of water when the specific factors will act on it.

### Salinization of water is it important?

Do you know that the density of water changes depending on its salinity? It means the freshwater, like the water you drink daily, has a different density than the saltwater, like the water in the sea. To make this issue clearer, the bigger density will have seawater, not freshwater. What is the exact value of seawater in lb/ft3? Let’s see: the density of seawater is 63.9262 lb/ft3. Do you know that this density is about 1.5 lb/ft3 bigger than the density of freshwater which is equal to 62.4264 lb/ft3?

### Freezing water and density

You probably know that, in the context of the temperature, there are 2 specific points of water. One of them is the freezing point. Water starts freezing when the temperature reaches 0 degrees Celsius. As you may know, the water neutral point is at 4 degrees Celsius. This showing clearly that at 0 degrees Celsius density of water will change. So what is the value of water density in lb/ft3 at the freezing point? It is exactly 62.421. The basic water density at 4 degrees Celsius is equal to 62.4264 lb/ft3, so these 2 results do not differ significantly as you see.

## What is max density of water?

The water density, as other values which are not constant, has its own maximum. This point is described for water which meets 2 conditions. What are they? It must be freshwaterwith a low level of salinity. The first condition behind us. This freshwater should have the temperature at 4 degrees Celsius too, and that’s all conditions. So what about the maximum water density value in such conditions? Have a look: it is exactly 62.4264 lb/ft3. Because of many decimal places, it may cause some problems with remembering it, so we give you also a simplified result: 62.4 lb/ft3.
