Answer
$\mu=5\ast10^{-5}\left[\frac{N.s}{m^{2}}\right]=10.4\ast10^{-7}\left[\frac{l b.s}{f t^{2}}\right]$
Work Step by Step
$1~{\mathrm{poise}}=10^{-1}\left[{\frac{N s}{m^{2}}}\right]$
$\mu\,=\,5\ast10^{-\,4}\ast1\,0^{-\,1}\!=\!{5}\ast\ 10^{-\,5}\left[{\frac{N.s}{m^{2}}}\right]\,(S I\,u n i t s)$
$\mu=5*10^{-5}*2.089*10^{-2}=10.4*10^{-7}\left[\frac{l b.s}{f t^{2}}\right](\mathrm{british~units})$
