Please provide any two values to the fields below to calculate the third value in the density equation of .
The density of a material, typically denoted using the Greek symbol ρ, is defined as its mass per unit volume.
The calculation of density is quite straightforward. However, it is important to pay special attention to the units used for density calculations. There are many different ways to express density, and not using or converting into the proper units will result in an incorrect value. It is useful to carefully write out whatever values are being worked with, including units, and perform dimensional analysis to ensure that the final result has units of . Note that density is also affected by pressure and temperature. In the case of solids and liquids, the change in density is typically low. However, when regarding gases, density is largely affected by temperature and pressure. An increase in pressure decreases volume, and always increases density. Increases in temperature tend to decrease density since the volume will generally increase. There are exceptions however, such as water's density increasing between 0°C and 4°C.
Below is a table of units in which density is commonly expressed, as well as the densities of some common materials.

The density calculator will help you estimate the relationship between the weight and volume of an object. This value, called density, is one of the most important physical properties of an object. It's also easy to measure.
If you want to know how to find density, keep reading. This article will provide you with the density formula, which this calculator is based on. You'll also learn how the density of water changes under different circumstances.
We will deal with these questions:
Or you can use our density calculator to make it a breeze!
The fastest way to find the density of an object is of course to use our density calculator. To make the calculation, you'll need to know a few other values to start with. Make a note of the object's weight and volume. After typing these values into the density calculator, it will give you the result in kilograms per cubic meter.
If all you need is to convert between different units, just click on the units for density and select your desired units from the list. If your unit is not there, you can use our density conversion calculator. Plug in your result there, the tool will convert it into:
Sometimes people are looking to convert grams into cups. If you know the density of the product as well as its weight in grams, you can find the volume of the ingredient in cups.
Allow us to throw in a bit of a curve ball here by reminding you that if you want to calculate the density of pixels on your screen, this is not the calculator your looking for, try this one.
Another way to calculate the weight to volume ratio of an object is to use the density formula. The calculation is not too complicated as you only need to do one operation to find it.
The density formula is as follows:D = m / v,
For most purposes, it's enough to know that the density of water is 1,000 kg/m3. However, as with almost all materials, its density changes with temperature. However, we have a slight, but a super important anomaly when it comes to water. While the general rule is that as temperature goes up, the density lowers, water behaves differently between 0 °C and 4 °C.
If you cool water from room temperature, it becomes increasingly dense. However, at approximately 4 °C degrees, water reaches its maximum density. How's this important? It makes it much harder for lakes to freeze completely in the winter. Since the water at 4 °C is the heaviest, it falls to the bottom of the lake. The colder water stays at the surface and turns to ice. This phenomenon, coupled with a low thermal conductivity of ice, helps the bottom of the lake stay unfrozen, so that fish can survive. It is this same principle that scientists think helped life get started on Earth. If water froze from the bottom up, then life never would have gotten the chance.
There are other aspects which affects water's density. It changes slightly whether it is tap, fresh or salt water. Every dissolved particle inside a body of water affects its density.
The density of a material is the amount of mass it has per unit volume. A material with a higher density will weigh more than another material with a lower density if they occupy the same volume.
The formula for density is the mass of an object divided by its volume. In equation form, that's d = m/v, where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m³.
Of the eight planets in the Solar System, Saturn has the lowest density at 687 kg/m³. This is much less than the density of water at 1,000 kg/m³. So, if you could put Saturn on a body of water, it would float!
Osmium is the densest element on the periodic table that occurs naturally, with a density of 22,590 kg/m³. It is combined with other metals to make the tips of fountain pen nibs, electrical contacts, and in other high-wear applications.
