Hey guys, I'm currently taking chem over the winter and it's a really sped up course for me since I have no background on it. I was wondering if anyone can explain the steps in these 2 problems. Thank you.

1. Convert m (cubed) to L

I know how to convert when there's a prefix but I don't understand what steps to take for this type of problem.

2. 25.5 mg+25.5cg+25.5g

I think we have to convert all to the same unit but I don't quite understand.

1. 1 cubic meter = 1000 Liters.
2. You need to convert them all to the same units. What is the end unit? For instance, 25.5 mg = 25.5x10^-3 g.

Also, this is not a HW help site.
