    I'll show you with an example. A) 10.5g to kg from that table in the link \(\sf 1 kg = 1000 g\) Now we need to use dimensional analysis - that just means we need to use the value they gave us and rearrange it to cancel out the "g" units and leave the "kg" units. to do so we need the "g" at the bottom and the "kg" at the top: \(\sf \dfrac{1kg}{1000g}\) Now we just multiply by our value 10.5 g, the "g" units cancel out \(\sf \dfrac{10.5g}{1}*\dfrac{1kg}{1000g}=\dfrac{10.5\cancel g}{1}*\dfrac{1kg}{1000\cancel g}\) Using a calc, were left with: \(\sf \dfrac{10.5kg}{1000}=0.0105~kg\)
