Kgf / cm*cm

[Mohit Pandey]

Can any one tell me what is kgf / cm*cm of Physics?
I found it in --The pressure in a water pipe is 3 kgf / cm*cm.

I’ll hazard a guess that “kgf” stands for “kilogram force”, and means “the force required to accelerate a kilogram mass by the acceleration of gravity at the earth’s surface”, or, roughly 1 kgf = 9.8 Newtons.

“/ cm*cm” is just an awkward way of writing , or “per square centimeter”.

So 1 kgf/cm*cm = about 9.8 N/cm^2 = 98000 N/m^2 = 98000 Pa

I didn't knew the use of 'latex'.

Thank you for your answer. I think you are correct.

Actually, 1 kgf/cm² is very close to the average atmospheric pressure, and in technology kgf/cm² or atm were often considered as interchangeable.
"atm" stands for "atmosphere", "ata" was used for "atmosphere absolute" and "ato" for "atmosphere overpressure".
1 kgf/cm² is also the pressure of a 10 m water column. "meter water column" was also used as a unit for pressure.
The SI-system made all this units obsolete
