Pressure Load

Hello,

 

I'm optimizing a rear wing for a racing car and I have one question:

 

I want to apply a 400kg load (pressure) on a area of 494000sqmm.

 

After selecting the elements on which to apply the pressure, should I enter 0.00799 on the Magnitude? Or 1.442e-7?

 

The difference is that the second value is the first divided by the number of elements (55412). 

 

I have searched around and done some tutorials but in some, the magnitude is the value of the pressure and in others, the magnitude is the pressure divided by the number of elements. 

 

Can someone help me please?

 

Thank you very much!
