pressure -- Torr which is equivalent to mmHg, Pascals or kPa, atmospheres, psi, inches Hg Volume -- usually liters Temperature -- Kelvin or Celsius which must be converted to Kelvin to be used in any gas law equations
The ideal gas constant ( R ) with a value of 0.0821 has units of liters·atmospheres per mole·kelvin (L·atm/(mol·K)). This means it describes how much volume one mole of an ideal gas occupies at standard temperature and pressure. The units reflect the relationship between pressure, volume, temperature, and the amount of substance in the ideal gas law equation, ( PV = nRT ).
Pressure, volume and temperature, and moles of gas are the four principal variables to describe a gas (for example, see related questions on Ideal Gas Law and others). The standard units are: Pressure: atmospheres (atm) Volume: liters (L) Temperature: Kelvin (K) Number of moles are measure in, well, moles.
Length: metreMass: kilogram Volume: litre temperature: Kelvin.
The pressure at standard temperature and pressure (STP) is 1 bar.
These are the corresponding units, if that's what you mean: mass: kilogram volume: cubic meter temperature: kelvin
Gay-Lussac's Law relates the pressure and temperature of a gas at constant volume. The units for pressure are typically expressed in atmospheres (atm), pascals (Pa), or millimeters of mercury (mmHg), while temperature is measured in Kelvin (K). The law states that the pressure of a gas is directly proportional to its absolute temperature. Thus, as temperature increases, pressure increases, provided the volume remains constant.
The scale divisions indicate the value of measuring units of volume, temperature, pressure, etc.
You must know Pressure, and Volume , and Temperature when making accurate measurements of Gas quantity. Most of the world measures gas pressure in KiloPascal, volume in Cubic Metre, and temperature in degrees Centigrade . It is essential to use all Metric units Or all Imperial units, but Imperial units are only used by the USA now. The volume of all gases, changes with change of pressure and also with change of temperature. That is why you must measure all 3 units referred to .

When the temperature is increased, the volume of a container gets larger, and vice versa. This can be found by examining one of the fundamental laws of gasses, the combined gas law. It states that the product of pressure and volume, divided by temperature yields a constant value: pV/T=k Where k is a constant with units of energy/temperature. Thus, in order for k to remain constant, temperature and volume must be varied inversely to one another.

Temperature, Pressure, # of moles, volume of container. If you know any three of those you can find the remaning by equation PV=nRT, where P=pressure in atmospheric units, V=volume in liters, n=number of moles of the gas, R=universal gas constant (which, in this formula, is equivalent to .08206), and T=temperature in Kelvins (not centigrade, but kelvins).
The product of pressure and volume has the same SI base units as energy or work, which is measured in joules (J). This is due to the definition of pressure (P) as force per unit area (N/m^2) and volume (V) as cubic meters (m^3), where the units of pressure times volume results in joules (J).
