Now that you have the mass and volume, calculate the density, as follows: m / v. The water density calculator might give you more insights into this problem. The formula for volume depends on the shape of the object, but it's a simple calculation for a box: v length x width x thickness. Use the following calculator to convert a known density into various units. Every dissolved particle inside a body of water affects its density. To determine density, it is best to measure an objects mass and volume. It changes slightly whether it is tap, fresh, or salt water. There are other aspects that affect water density. If water froze from the bottom up, then life never would have gotten the chance. It is this same principle that scientists think helped life get started on Earth. This phenomenon, coupled with a low thermal conductivity of ice, helps the bottom of the lake stay unfrozen, so that fish can survive. The colder water stays at the surface and turns to ice. ![]() Since the water at 4 ☌ is the heaviest, it falls to the bottom of the lake. How's this important? It makes it much harder for lakes to freeze completely in the winter. However, at approximately 4 ☌ degrees, water reaches its maximum density. ![]() If you cool water from room temperature, it becomes increasingly dense. While the general rule is that as temperature goes up, the density lowers, water behaves differently between 0 ☌ and 4 ☌. However, we have a slight, but a super important anomaly when it comes to water. However, as with almost all materials, its density changes with temperature. If you enter your two figures for mass and volume into the calculator, it will return the density. To calculate density, you divide the mass by the volume. We have prepared the grams to cups calculator specifically for that purpose.Īllow 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.įor most purposes, it's enough to know that the density of water is 1,000 kg/m 3. The density calculator uses the density formula: Density Mass Volume. 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. Sometimes people are looking to convert grams into cups. Plug in your result there the tool will convert it into: If your unit is not there, you can use our density conversion tool. 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. After typing these values into the density calculator, it will give you the result in kilograms per cubic meter. Make a note of the object's weight and volume. To make the calculation, you'll need to know a few other values to start with. The fastest way to find the density of an object is, of course, to use our density calculator. Or you can use our density calculator to make it a breeze! Try mixing oil and water and see how they separate into layers, with the less dense oil on top. An online density calculator determines the density, volume or mass of the object by considering any two of the variable involved in the density equation. When you mix two or more substances, the most dense substance sinks to the bottom, whilst the least dense substance is more buoyant and floats to the top. This is why you should never comment on your Auntie Mabel's sponge cake by describing it as dense: she was probably going for something a little more airy.ĭensity is also what makes things float or sink. A pound of feathers is filled with airy space, so it's not very dense at all, while a pound of lead feels much more solid, so it's more dense. For an equal amount of space it takes up (volume), lead weighs much more than the feathers (mass).ĭensity can also be thought of as how compacted or compressed a substance is. So if the question was, 'Which weighs more: a 500ml jug full of feathers or a 500ml jug full of lead?' then the answer would be the lead. What is density?ĭensity is the mass per volume - not just the straight-up mass. Read on to find out exactly what density is, how it works, and how to calculate density. ![]() Although the feathers and the lead both weigh exactly the same (um, a pound), their density is wildly different, and we can sometimes mentally conflate weight and density - even though they're different concepts. If you've ever been fooled by the old question, ' Which weighs more: a pound of feathers or a pound of lead?' then you wouldn't be alone. To calculate density: p = m/V To calculate mass: m = pV To calculate volume: V = m/p
