Kilogram force per square meter
Kilogram force per square meter (kgf/m²) is a unit from the force of one kilogram under standard gravity (9.80665 m/s²) on an area of one square meter.
Pascals
Pascals (Pa) are the SI units of pressure named after the French mathematician Blaise Pascal. It is defined as one newton per square meter (N/m²). Since the pascal is a relatively small unit, kilopascals (kPa), megapascals (MPa), and gigapascals (GPa) are often used for practical applications.
