The main thing to keep in mind, is the base unit must be the same for each measurement. For example,
when calculating the volume of a box and you measure the length, width, and height in inches then the volume
will be in cubic inches.
It doesn't matter what the measurement unit is as long as all measurements use it. If you measure
in centimeters then the volume will be cubic centimeters. If you measure in miles then the volume will
be cubic miles. etc.
If you measure the length in inches and the width in feet, the result will be incorrect. Make sure
to first convert all measurements to the same base unit before using the calculator.
Once you have the volume of the object in cubic form, you can then easily convert that to gallons,
liters, or whatever else you need on the volume conversion page.
The radius is not the diameter
Another common mistake is entering the diameter of an object when the radius is asked for.
The radius is 1/2 the diameter. So if you only know the diameter, be sure to divide by 2 to determine
the radius.
You can calculate any measurement
The calculators were designed to calculate the missing measurement. Normally you have all the
measurements and need to know the volume. But if you know the volume but are missing something else,
the calculator will find it. Just leave whatever field you need blank.
