  The major difference is compressibility. Generally, liquids are practically incompressible. So just knowing the mass flow rate and density, volume flow rate can be calculated. It’s not so simple for gases

  A fluid is anything that flows. A box of marbles is a fluid.

  First of all: Sorry, I made a mistake yesterday. I ment to say liquid but translated it wrong in my head

  Now to your question, they are similar in some aspects, that’s what makes gasses and liquids both be considered fluids, so fluid dynamics apply to both for example.

  The difference is how much the molecules in the liquid or gas interact: A lot in the liquid, not significantly in most gasses under standard conditions.

  And the things is, the SLPM measure apparently relies on a characteristic of ideal gasses, that one mol of gas particles under standard conditions always takes a fixed volume 22.41 l. So now I’m confused why they would use it for hydraulic fluid, which sounds like a liquid to me.
