The volume mixing ratio measures the volume of a substance (the solute) contained within the
unit volume of a mixture (the solution). It is the ratio of the partial volume of the solute
to the volume of the mixture. It is frequently used with ideal gases, since, in this case,
it has the same numerical value as the ratio of the partial pressure of the solute to the
total pressure or as the mole fraction.

**Usage:**
Type the value to convert into the field, behind which you find the unit.
Click on any empty space in the window or on the "calculate" button.
Read the result in the other fields.
Use the "reset" button to reset your calculation.
Move the mouse over a unit or click on it to read its full name.

**Example:**
What is the volume mixing ratio of a mixture of 230 cubic inch of a substance in
1 cubic foot of the mixture. Type "230" into the field behind which
"in^{3}ft^{-3}"
is written. Click on any empty space in the window or on the "calculate" button.
Read the result in the other fields (e.g. 13.31 %).
