#### Answer

a) $km/s$ b) $mm$ c) $Gs/kg$ d) $mm*N$

#### Work Step by Step

We are given a pairs of units and asked to convert them to more appropriate SI units a) $m/ms * \frac{1km}{1000m}*\frac{1000ms}{1s}=km/s$ b) $\mu km*\frac{10^-6}{\mu}*\frac{10^3m}{1km}=10^{-3} m = mm$ c) $ks/mg*\frac{1000s}{1ks}*\frac{1Gs}{10^9s}*\frac{1000mg}{1g}*\frac{1000gN}{1kg}= Gs/kg$ d) $km*\mu N*\frac{1000m}{1km}*\frac{1000mm}{1m}*\frac{1N}{10^6 \mu N}= mm*N$
