Pre-College Issues High School Life

<p>So, the school year hasn’t even started for me yet and my AP chem teacher sent me work in the mail. Needless to say, I’m a bit confused with the material. So I have a few questions for those of you that have taken this class.</p>

<li>How many nm = 1 mm?</li>
<li>How many ms = 1 s?</li>
</ol>

<p>Also I’m not quite sure if I’m converting my units correctly. In one problem I had to convert 3.5 x 10^-9m to picometers. If found that one pm = 1x10^-12 meters. I got an answer of 0.2 x 10^-3 … but I’m not really sure if that’s right. </p>

<p>Thanks in advance if you can help me with any of this. =]</p>

<p>I think I figured out my second question: 1000 ms = 1s, right?
the "s" stands for second .. which I didn't know. LOL</p>

<p>but if you can offer me any help on the others, I'd appreciate it. =)</p>

<p>1 nm = 10^-9 m
10^3 x 10^-9 m = 10^6 m = 1 mm
1000 nm in a mm.</p>
