But you and I have something to do with each other: to generate a pressure of 1 MPa, you need to apply about 10 kg of pressure on the plane of 1 square centimeter or the size of the surface of the object. These are two different physical quantities. You can't say that 1 MPa is equal to several kilogram forces. The kilogram force is the unit of force: 1 kg force = 9.8 Newton, 1 MPa = 1000000 PA, and "MPa" is the unit of pressure, one square meter. The pressure on the plane or the surface of the object is one Pascal [1pA = 1n / (m × m)], and the tonnage of the bending machine is related to the MPA on the pressure gauge.
