Density Calculator

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 on 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:

• How to find density;
• What density formula is; and
• What affects the density of water.

1. Determine the weight of an object. For example, a glass of water weights $200 \ \mathrm{grams}$ net (not including the glass).
2. Find out the volume of an object, e.g., by using the volume calculator. In our example, it's $200 \ \mathrm{cm^3}$.
3. Divide weight by volume. $200 \ \mathrm{g / 200 \ cm^3} = 1 \ \mathrm{g/cm^3}$
4. Optionally, change the unit. $1 \ \mathrm{g/cm^3} = 1 (1/1000 \ \mathrm{kg}) / (1/1000000) \ \mathrm{m^3} = 1000 \ \mathrm{kg/m^3}$

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 tool. Plug in your result there; the tool will convert it into:

• Kilograms per cubic decimeter;
• Pound per cubic foot;
• Pound per cubic yard; or
• Pound per US gallon.

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. We have prepared the grams to cups calculator specifically for that purpose.

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 you are looking for; try PPI calculator instead.

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:

where:

• $D$ - density;
• $m$ - mass; and
• $v$ - volume.

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 that affect water density. It changes slightly whether it is tap, fresh, or salt water. Every dissolved particle inside a body of water affects its density. The water density calculator might give you more insights into this problem.

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.

1. Measure the object's mass (or weight) in kilograms.
2. Measure the volume of the object in m³.
3. Divide the mass by the volume.
4. You will then have the density of the object in kg/m³.

1. Look up the density of the material the object is made of in kg/m³.
2. Measure the mass (or weight) of the object in kilograms.
3. Divide the mass by the density.
4. You will then have the volume of the object in m³.

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.

1. Measure the mass (or weight) of the liquid with some scales and convert to kilograms.
2. Measure the volume of the liquid with a measuring jug and convert to m³.
3. Divide the mass by the volume.
4. You will then have the density of the liquid in units of 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.

1. Measure the mass (or weight) of the irregular object using scales and convert to kilograms.
2. Measure the volume of the irregular object. One way to do that is to submerge the object in a measuring jug of water and record how much the volume increases by. Convert the volume to m³.
3. Divide the mass by the volume.
4. You will then have the density of the object in units of kg/m³.

1. Note the mass of Earth in kilograms, which is 6×10²⁴ kg.
2. Look up the volume of the Earth in m³, which is 1.1×10²¹ m³.
3. Divide the mass by the volume.
4. You will then have calculated the average density of the Earth and get a value of 5,500 kg/ m³.

1. Look up the density of the material the object is made of in kg/m³.
2. Measure the volume of the object in m³.
3. Multiply the density by the volume.
4. You will then have the mass of the object in kg.
