kg/cm^2 is the unit of??

Question

well this means mass/area doesnt it? ive heard its some unit of pressure, can anyone please clarify??

thanks in advance.

Answer 1

It's not a unit of pressure. The equivalent of pressure units in metric system is N/cm^2 or more commonly known as pascal, where N = kg*m/s^2. Kg/cm^2 is a unit of density, surface density that is. Sometimes, you would have raw materials with difined thickness. Knowing the density by volume of the material becomes inconsequential. If you know the surface density and the area of the material, you can figure out the mass of the material without putting it on a scale.

Answer 2

I have seen it used as pressure, but it's not a very logical unit to use as kg is the units for mass, not force. In this case one kg refers to the weight of one kilogram of mass (which is 9.81 Neutons).

It is a convenient unit of pressure because 1kg/cm^2 is within 2% of one atmosphere pressure.

Answer 3

because pressure=force/area.force's unit is N(Weight=mass times g),area's unit is cm^2..so the unit u said can be the unit of pressure..but i prefer Pa as pressure's unit

Answer 4

It's a unit of pressure, very similar to PSI (pounds per square inch), in this case, kilos per square centimeter.

It assumes that the acceleration of gravity is 9.8 m/s², that is, that you are on Earth at ground level, and it's not the International System unit, so I personally would much rather use Pascals (N/m²).

Answer 5

Kg/cm² is a unit of pressure i.e. 10kg acting on an area of 1cm² is 10kg/cm² pressure.

In Imperial 1kg/cm² (1 bar), is equal to 14.3 psi.

When you inflate your car tyres you use 'Bar' or 'Psi', I don't think I've seen a tyre pressure gauge reading Pascals or Newtons !!, therefore, as 1 bar = 1kg/cm², then kg/cm² is a pressure reading.
