Let me make it clear that I'm a moron in math, and thus, I'm also a moron in Physics at this point. I just bombed a quiz on converting Base units... so I really want some help. Please help me out, but if you dont know, dont act like you do. Thanks in advance.
Example -
C3PO weighs 200 ibs, convert his weight to metric kilograms.
1 kg = 2.2 ibs, so it's 2.2 ibs divided by 200 ibs, which equals 90.9, so C3PO weighs 90.9 kilograms?
Example -
Blue Snaggletooth stands 3 ft. tall, convert his height to millimeters.
1 ft. = 12 inches, so 12 times 3 (ft) is 36. So Blue Snaggletooth is 36 inches. 1 inch = 2.54 centimeters, so 2.54 centimeters multiplied by 36 inches is 91.44 centimeters. Slide the decimal to the right to convert centimeters to millimeters, making Blue Snaggletooth 914.4 millimeters tall?
Example -
A squad of Dewbacks patrol a 12 mile perimeter, convert the miles to kilometers.
1 mi. = 1.6 km, so 1.6 km multiplied by 12 mi is 19.2 km. The dewbacks patrolled 19.2 km?
Please let me know if I'm correct, if not, please correct me and explain. Thanks a lot.

Everything looks right to me Brad! I don't know jack about Physics, but I'm pretty good with math (I'm an auditor), and all of your calculations there check out just fine with me...
-
Thanks a ton, (Jedi)Mac. As I was telling (Jedi)Chris, I got kicked out of math class doing those really important days, so I never really have understood all of the formulas. Now I'm having to make-up for them days I wanted to be a badass. :-[
Hopefully I'll be able to recover from that quiz and make a A this 6 weeks.

Brad sorry I missed this one...
keeping track of units is a snap
Converting mm to feet
10 mm * 0.039 in * 0.0833 ft = 0.033 ft
mm in
What you are doing when converting is multiplying the original number by 1/1
0.039 in = 1 mm ... 0.039 in/1 mm = 1
The easy way to check is to make sure your units cancel on both sides of the equation, so the mm and in cancel above and you are left with ft
Hopefully I am not too late :-\
If you have any other question feel free to ask, I've had a Semester of Physics at College ;)

So does that mean that I goofed this up Scott? I didn't really understand what his questions had to do with Physics, but from a purely mathematical point it looked like his examples and answers checked out just fine...
If I just caused you to fail your class, let me know Brad, and I'll send a note to your teacher explaining that it was all my fault! :'(
-
Nope he's right, just showing him some tricks on how to keep track of units better ;)
-
Phew! Thank God. Thought I was losin' my mind there for a minute. I would hate to have ruined Brad's chances to get into a good college! See Brad, you were right all along! You don't need us accountants and engineers to help ya' out! ;)
-
Good ole' JediChris helped Brad out via AIM also, I think he is set straight, though I am no math major. Simple equations I believe.
-
All of you guys have helped me out a ton w/ this stuff, thanks a lot.
Now our class has gotten into "real" physics... The teacher is talking about speed/velocity/etc, and the only problem is that our teacher simply doesn't teach... She has no connection whatsoever to the students, and even the meanest teacher I've ever had at least tought SOME of her kids.
I just realized the other day that the class is officially titled "Advanced Conceptual Physics", I didn't know I was in advanced. ::) I'm a moron.
Luckily I didn't bomb that initial quiz though, I scored a 73% so at least it was a passing grade.

Now our class has gotten into "real" physics...
Then you can count me out for any further tutelage! I hate science. I somehow got through all of high school with only taking Biology - no Physics or Chemistry. Not sure how, but I'm GLAD I did! Good luck Brad, you're gonna need it! But I'm sure that smarty pants engineer fella that roams these parts will still be able to help you out! ;)
-
Yes, from now on you will have to get help from that engineer of ours. You have a computer question come to me. Oh, wait- I forgot you have a Mac. Well, my statement actually is right, if you have a real COMPUTER I can help you out. ;)
Just kidding!! ;D All of the loyal Mac users please don't attack me, it was only a joke. ;)
-
As much as my Mac freezes and crashes, as Chris has seen probably 15+ times while in the middle of a chat w/ me, I'm not about to defend the Mac...
It's a love-hate relationship, I guess. I like the look & feel, I hate the freezes and lack of games.

Any time you need help Brad don't hesitate to ask :)
