# If the absolute pressure of gas is 550.280 kPa, it's gage pressure is what?

Subtract atmospheric pressure from that to get gage pressure. Atmospheric pressure varies with altitude and weather, but the average atmospheric pressure, at sea level, is 101.325 kPa.

550.280 - 101.325 = ?

if the absolute pressure of a gas is 550.280 kPa, it's gage pressure would be what?
