Dear Abraham
plot your normalized impedance value on the smithchart and draw a circle passing through that point with your centre at r=1 point and you have the vswr.

sorry didnt finish the complete answer. after you draw your circle,look at the point where it passes through the centre of the smith chart,measure the value using a scale and compare it with the length provided in the scale provided on the bottom.
Hope that helps
