If a star is 190pc away from Earth what is this distance in AU?

The parsec (parallax of one arcsecond; symbol: pc) is a unit of length, equal to just under 31 trillion (3.1×1013) kilometres (about 19 trillion miles), 206265 AU, or about 3.26 light-years.

So 206265 X 196 = ?????? AU
You can do the hard bit.
