# Expressing height in Inverse GeV

My physics professor has asked that I express my height in GeV-1. I am about 1.8 meters tall. He has also given me a wavelength equation which goes as follows. wavelength=h/mc. He has also noted that h=c=1. Does anyone have a clue about how to go about converting these units?

Well, at the moment all I can think of is E = h$\nu$ = hc/$\lambda$ which means $\lambda$ = hc/E, and if h = c = 1, then $\lambda$ = 1/E which would have units of 1/GeV if one puts E in GeV.
