Gas can be measured by volume (in litres), by mass (in grams/kilograms etc or, in chemistry a mole).
liters
You need a lot of gas to do this, but you start by weighing an empty cylinder. You then put a measured quantity of gas in the cylinder and weigh it again.
A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity.

Thickness of door is not measured in km. Kilometer is a big quantity.
The volume of gases is measured with gas-meters.
A wattmeter is used to measure the power of a load.
if you are referring to the gas you buy at gas stations, it is measured in litres. if the sign out front says 95.7, that means it is 95.7 cents per litre.
