How do I convert measure in metric system? @jim_thompson5910

OpenStudy (j2lie):

jimthompson5910 (jim_thompson5910):

how far did you get?

OpenStudy (j2lie):

Number 11 for the metric system ladder method.

jimthompson5910 (jim_thompson5910):

so we have 256 place a decimal point between the first two digits (2 and 5) to get 2.56 how many spots must we move the decimal to get back to 256 ?

jimthompson5910 (jim_thompson5910):

oh wait, I'm in the wrong section

jimthompson5910 (jim_thompson5910):

ok so 6 L to mL

jimthompson5910 (jim_thompson5910):

use something like this chart http://www.notredameacademy.ca/docs/homework/Lesson%201a%20-%20Metric%20Ladder%20Powerpoint.pdf

OpenStudy (j2lie):

and wrong number too. lol. I got 6000 L.

jimthompson5910 (jim_thompson5910):

`6 L = 6000 mL` I think you meant to say?

OpenStudy (j2lie):

oh I was right. 6000 mL

jimthompson5910 (jim_thompson5910):

yes `6 L = 6000 mL` is true

OpenStudy (j2lie):

ok.

OpenStudy (j2lie):

OpenStudy (j2lie):

jimthompson5910 (jim_thompson5910):

For #2 are you saying that `1.3 g = 0.13 kg` ?

OpenStudy (j2lie):

yes.

jimthompson5910 (jim_thompson5910):

that is incorrect

jimthompson5910 (jim_thompson5910):

go to this link for the basic template http://www.notredameacademy.ca/docs/homework/Lesson%201a%20-%20Metric%20Ladder%20Powerpoint.pdf start at the "basic unit" block. In this case, it's grams then move until you get to the "kilo" block. Count out the number of spaces and take note of the direction you move

OpenStudy (j2lie):

I moved to the left 3 times.

jimthompson5910 (jim_thompson5910):

so you move the decimal point in `1.3` three places to the left

OpenStudy (j2lie):

Yes, but you don't need the zeroes in this case?

jimthompson5910 (jim_thompson5910):

what do you mean?

OpenStudy (j2lie):

Never mind. Do you need to add zeroes if you move to the left, because I did that for every problem like it?

jimthompson5910 (jim_thompson5910):

yes as you move the decimal point to the left, you will have 0s in between so `1.3` turns into `0.13` after moving the decimal point once to the left then we will have `0.013` after 2 moves to the left then we will have `0.0013` after 3 moves to the left

OpenStudy (j2lie):

So you need the zeroes?

jimthompson5910 (jim_thompson5910):

yes if you leave them out then you'd get back to 0.13 or something

OpenStudy (j2lie):

Ok. Can you check the rest to make sure they are right. I'm sorry.
