Determine the weight of an object. For example, a glass of water weights 200 grams net (not including the glass).
Find out the volume of an object. In our example, it's 200 cm3.
Divide weight by volume. 200 g / 200 cm3 = 1 g/cm3
Optionally, change the unit. 1 g/cm3 = 1 (1/1000 kg) / (1/1000000) m3 = 1000 kg/m3
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 thee, you can use our density conversion calculator. If you plug in your result there, the tool will convert it into:
kilograms per cubic decimeter
pound per cubic foot
pound per cubic yard
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.
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.
Density formula
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
Where:
D - density
m - mass
v - volume
Density of water
For most purposes, it's enough to know that the density of water is 1000 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 also 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.

Answer:
A classroom environment is different from most social environments that a student may encounter in his academic life. What is expected of me? is a question most commonly asked by every student. Students who differ in personality, interests, learning styles, and levels of thinking can be seen in any class. In such a situation and for the smooth running of a class, certain rules, regulations, moral standards, and procedures are created and have to be strictly followed by students in classrooms. The guidelines that have to be followed by students to maintain acceptable classroom environment are known as “Classroom Etiquettes”.
Classroom rules can be made by the institution or by the instructor; however, it is always helpful to maintain appropriate classroom situations. As a student, this is expected of you irrespective of:
Who you are
Where you are from
What your ability is
What your motivational level is
What your personality is
A student is expected to maintain and follow rules and regulations which are put forward for the best of all.
Top Classroom Etiquettes
Arrive to Class on Time
There are always going to be days when a previous professor keeps you late, or you wake up late, or it takes you too long to find a parking space, but the point here is do not be habitually late to class. Whether you mean it or not, regularly arriving late to the class, signals a level of disrespect to the class and the teacher. If you have problems getting to class on time, find a way to solve them. And on those rare days when you do arrive late, remember to enter the room by excusing yourself softly and quietly and not make a big scene.
Turn Off Your Cell Phone
Most beepers and cell phones can be set to vibrate rather than produce a sound, so they should be less of a problem. These devices should be turned off if they cannot be set to a silent mode. Some phones are pretty noisy even on vibrate. Of course, you should not answer your cell phone during class. If you are expecting a really important call (e.g., wife going into labor, call for an interview), then it might be a good idea to inform the instructor before class so it’s less of a distraction if you leave the classroom to take the call. You should also sit near a door so you can make an unobtrusive exit.
