standard pressure
standard pressure[′stan·dərd ′presh·ər] (meteorology) The arbitrarily selected atmospheric pressure of 1000 millibars to which adiabatic processes are referred for definitions of potential temperature, equivalent potential temperature, and so on. (physics) A pressure of 1 atmosphere (101,325 newtons per square meter), to which measurements of quantities dependent on pressure, such as the volume of a gas, are often referred. Also known as normal pressure. standard atmospheric pressureThe pressure exerted by a standard atmosphere; also see atmospheric pressure.standard pressure
