Pressure - Force per unit area The pressure is the force per unit area. The standard unit for pressure is the Pascal, which is also called as newton per square meter. Liquids and gases - Fluid A fluid is a substance that continually deforms under an external force. The fluid is a substance that can flow. Liquids and gases are known as fluids. Atmospheric pressure - barometer Atmospheric pressure is measured by using an instrument called a barometer. The barometer uses height of the mercury column to indicate the pressure. Pascal - unit of pressure The standard unit for pressure is the pascal, which is equal to newton per square meter.
