When you introduce a load of pressure on one area in ansys, in what units is it indicated?. I have read that the units are [lb/in^2] and to pass it to [kpa] it is necessary to multiply by 6.89. Is it true?
Excuse me for my poor english. Thank you very much.

I am not sure where you read those units, but everything from geometry to loads, is dimensionless.

1. And if you apply a pressure of 1000 in an area. What pressure is it equivalent in an experiment in the reality?

2. I mean, if I have an object that weighs 10 kg placed on a table, I was understanding that I had to multiply for 10 for the acceleration of the gravity and this it would be the force in newtons. And later I would have to divide this force by the surface in which I apply the force and this it would be the pressure in N/m^2

You can choose any system of units in your model. Just make sure you are consistent. A useful document in the download section of this site is this (http://www.polymerfem.com/modules.php?name=Downloads&d_op=getit&lid=46url).

Thank you very much. I think that I have already understood it. I expect to have success

i am not an expert in Ansys but i read somewhere that /units command will allow u to set the units u want to use in the analysis. its like if u want to use SI then type /units, SI in the beginning of the analysis or for CGS type/units, CGS. see /units in the help of ansys.
