Weight can be expressed in kg. What is the mass
The international unit of weight is cattle
The international unit of mass is kilogram
The unit of weight is expressed in kg because of habit, which is not standard, but it is in line with the habit of most people or industry regulations
Is mass the same as weight? Why is mass also expressed in kg? There is a question: the mass of an elephant is about 5 - so the mass here can be understood as
What are the concepts of weight and mass?
In physics, mass and weight are two completely different quantities. Mass means the amount of matter contained in an object, while weight means that the object is subject to the gravity of the earth (regardless of other forces)
Because gravity g = mg, (M is the mass, G is the acceleration of gravity, the size is 9.8), so using gravity to express the number will be very large, and using mass will be more convenient, but mass must not be understood as weight
The unit of mass is kg, G, etc., and the unit of weight is n, which is a force
How much kg (or MPa) is inHg equal to in air pressure?
1In=25.40mm
1 mm Hg - 133 Pa
1 inch Hg = 3,386 Pa
1 atm = 1.01325 bar = 101.3 kPa = 14.696 psi (lbf/in2)= 760 mmHg =10.33 mH2O = 760 torr = 29.92 inHg = 1013 mbar = 1.0332 kgf/cm2 = 33.90 ftH2O

One is that the normal should be kg, and the other is that in practice, kgs is usually used according to the original documents, But today, I'm particularly puzzled about this problem. I want to know the correct way to write it. In addition, for example, the title quantity on the packing list: quantity (PCS) or quantity (PC). I feel that this PC means the unit of quantity is PC, which only means the unit, so I don't need to add s? Is the corresponding sample book N.W. (kg) written correctly, or N.W. (kgs)?
