The S.I. unit for the measure of the pressure is the Pascal (Pa). 1 Pascal corresponds to
[tex]1 Pa = 1 N/m^2[/tex]
We can convert the number given by the problem into Pascal:
[tex]8200 N/m^2 = 8200 Pa[/tex]
And since [tex]1 Pa = 10^{-3}kPa[/tex], we have
[tex]8200 Pa = 8200 \cdot 10^{-3}kPa =8.2 kPa[/tex]
