Question

1. 65g= ___mg?
2. 6.3cm= ______mm?

Answer 1

g- gram
mg- milligram
cm- centimeter
mm- millimeter

Answer 2

1g = 1000mg
1cm = 10mm
Does that help? (I'll give you a medal if you write the right answer)

Answer 3

65g= 65000mg?
6.3cm= 63mm?

Answer 4

Yup! :D

Answer 5

yay! :D thankyou!

Answer 6

No worries :D

Answer 7

When you have these kind of problems, always set them up first.
mg = 1.65 g x 1000 mg/1 g. The g cancel out and you will be left with mg. You have to know the conversions first.
You will never go wrong with this method. It is called dimensional analysis.

Answer 8

I had learned that in biology yesterday i understand the concept but i find it to be a tad bit confusing. Like when it comes to deci, centi and milli. I don't know how to cancel them out like this is the problem that i'm stuck on.
8g __ 30cg im suppose to compare metric measurements but my biology teacher wants us to show our work like this.

For example: 4L < 517cl
4L= 400 517cl
4L/ 1 x 100cl/ 1L

Answer 9

im suppose to see which one is greater.

Answer 10

Hmm okay, When you have is A ml greater than B L you need to convert to the same units, which you have done.

The cancelling out I learned to think of it like this:
If you put one thing the same on top of another of the same then they cancel each other out. (so x/x =1, so 1*anything = anything)
soo we are left with


That may be a strange way to see it, but it works in my mind so I remember it :)
