Density Calculator

Table of contents:
Have you ever wanted to find a density? What about learning the density formula? Do you know how to affect the density of water? Our density calculator answers all your burning questions. Learn about the relationship between volume and an object’s weight. 

Density is a valuable physical property and one that’s effortless to measure. Learn more about the density calculator and what it is below.

How Do You Find Density?

Finding an object’s density is a straightforward process. Learn how in a few steps below.

1.	Identify an object’s weight. 
A bowl of soup, without the container, is 400 grams

2.	Find the object’s volume. 
In this example, it’s 400 cm3

3.	Divide the object’s weight by the volume 
400 grams / 400 cm3 = 1 g/cm3

4.	 Play with the units. If you don’t like g/cm3, change it. 
1 g/cm3 = 1 (1/1000 kg) / (1/ 1000000) m3 = 1,000 kg/m3

5.	Too hard? Use a density calculator to calculate it for you. 

The beauty of a density calculator is you don’t need to do a whole lot of calculations. You need to know the object’s volume and weight and it takes care of everything else. Once you enter the information, the calculator offers an answer. 

When you get the information you seek, you can convert it to different units. Use a density conversion calculator or play with the options in the drop down menu. You can use pounds, kilograms, cubic feet, cubic yards, gallons, and more.

What is the Density Formula?

Finding the density of an object requires the use of a density formula. It is as follows: 

D = m / v

D = density
m = mass
v = volume

How to Measure Water Density

Water density is 1,000kg/m3. You may find it’s helpful to keep that information in the back of your mind when you make water density calculations. 

However, when you play with that water’s temperature, the density can change. Higher temperatures equate to a lower density. Water also behaves differently between 0-4 degrees Celsius. 

If your water is at room temperature and you cool it, the density skyrockets. When it hits four degrees, it will be at its densest. With dense water, lakes find it hard to freeze in winter. Heavy water will sink to the bottom of a lake, and cold water stays on the surface. It then forms an ice layer. 

Low thermal conductivity partnered with the cold water stops the lake bottom from freezing, allowing fish to survive. The water density can also change depending on whether the water is fresh, salt, or from the tap.
