Is the pressure in a perfect vacuum zero?

The inputs are P for pressure, V for volume, n for number of moles, R for the gas constant, and T for temperature. We can use various units for pressure and ... We can use various units of pressure, volume, temperature, and mole number to derive the unit of universal gas constant from the formula of the ideal gas law. A few examples without units can be used to clarify the equation further. Example 1. A steam system has a pressure of 10, volume of 3 and temperature of 100.
