To calculate pressure, divide the force (in newtons) by the area (in square metres). It is measured in newtons per square metre (N/m²). In Imperial (U.S.) measure, it is measured in pounds per square inch (lb/in.²) (psi). Also see atmospheric pressure , back pressure , boost pressure , center of pressure , clutch pressure plate , extreme pressure lubricant , mean effective pressure , oil-combination splash and pressure system , oil-full pressure system , oil pressure gauge , pressure bleeder , pressure cap , pressure radiator cap , pressure relief valve , safety pressure cap , and static pressure .
