The above 3 formulas are used for solving problems involving volume, mass and density.
If you know 2 of the 3 variables the third can be calculated.
As usual, here at www.1728.com, we have a calculator that will do all the work for you.
This ultra calculator is special by allowing you to choose among a
great variety of units (9 per category). Unlike other calculators, you are NOT
confined to inputting volume in liters, mass in kilograms, etc. making this calculator
quite versatile. Let's see some examples.
1) How much volume does a ton of water occupy?
FIRST CLICK ON WHAT YOU ARE SOLVING FOR  VOLUME
Enter 1 in the mass box and choose Short Tons from its menu.
Enter 1 in the density box and choose H2O Density from its menu.
Click CALCULATE and your answer is 32.036 cubic feet.


2)
The density (specific gravity) of gold is 19.3. How much is the weight of one cubic foot?
The most important step in using this calculator is:
FIRST CHOOSE WHAT YOU ARE SOLVING FOR.
In this case we are solving for weight or MASS so click on that button.
Enter 1 in the "volume" box and choose cubic feet from its menu.
Enter 19.3 in the "density" box and choose H2O Density from its menu.
Click the CALCULATE button and you will see this weighs 1,204.85 pounds. PLUS you get to
see the answer in 8 other different units !!
3) You are measuring 15 cubic centimeters of a liquid that has a mass of
17 grams. What is its density?
FIRST CLICK ON WHAT YOU ARE SOLVING FOR  DENSITY
Enter 15 in the volume box and choose cubic centimeters from its menu.
Enter 17 in the mass box and choose grams from its menu.
Click CALCULATE and your answer is 1.133 that of H2O Density (as well as 8 other units).
***** Weight of Water Calculator *****
4) What is the weight of 3.5 gallons of water?
FIRST CLICK ON WHAT YOU ARE SOLVING FOR  Weight of Water
The density input box automatically gets filled in with the value of 1 and so you only have to enter one number.
Enter 3.5 in the volume input box then select "Gallons" from its menu.
Click "CALCULATE" and you will see that 3.5 gallons of water weighs 29.029 pounds (as well as 8 other units).
***** Units of Density *****
Units of density (particularly when related to solutions) are generally reported as grams per cubic centimeter (g/cm³), which also equals kilograms per liter (kg/l).
If we use water as the standard, then the density (the specific gravity) of water is 1 gram per cubic centimeter or 1 g/cm³.
Just for example, the density of carbon is 1.83 g/cm³ and mercury's density is 13.55 g/cm³.
The unit for density in the International System of Units is kilograms per cubic meter (kg/m³) which also equals grams per liter (g/l).
These unts are 1,000 times larger than grams per cubic centimeter (g/cm³) and so the density of water in this unit is 1,000 kg/m³.
Here's hoping this calculator helps you with those math problems.
For easy readability, the answers are displayed in a "significant figure" format so you will
not see answers such as 77.3333333333333333.
Numbers larger
than 1,000 will be displayed in scientific notation and with the same number of
significant figures specified. You may change the significant figures displayed by
changing the number in the box above.
Internet Explorer and most other browsers, will display the answers properly but
there are a few browsers that will show no output whatsoever. If so, enter a zero
in the box above. This eliminates all formatting but it is better than seeing no
output at all.
