Simple Chemistry converting question?
Ok so see.. I'm really bad at chemistry and it's all very difficult and anywho I wanted to ask.. for example:
10.5g convert it into kg which is:
?kg=10.5g x 1kg/1000g= 0.0105kg
Would it be okay if I used 0.0001g instead or 1000g?
if I did use it the answer would be 105000kg.. would it be wrong or right? I just get confused with which one to use..
I'm sorry, see what I mean.. it is 0.001, if I used that would it be wrong, or is it a must that I need to use 1000?

A conversion factor is a ratio (fraction) of two quantities which are equal to each other, but expressed in different units.
Like 12 inches = 1 foot
We can make two conversion factors
12 in / 1 ft or 1 ft / 12 in
The conversion factor is set up so that we cancel out the units we don't want and leave the units we do. The units on the top and the bottom cancel out.
10.5 g x (1 kg / 1000 g) = 0.0105 kg
This works because 1 kg = 1000 g and the conversion factor is set up so that grams cancel out and leave you with kg.
Since 1 g = 0.001 kg we can also use this in a conversion factor:
10.5 g x (0.001 kg / 1 g) = 0.0105 kg
======== follow up ==========
It's obvious that one can get confused trying to decide whether to multiply by 1000 or divide by 1000. The solution to this conundrum is to use CONVERSION FACTORS. This will eliminate any and all confusion. You really have to work at it to get an answer wrong when using conversion factors.

You see 1kg=1000g
So if you ever want to convert some number in grams to kg unit follow this:
If 1kg is 1000g then what is 1gram?1/1000th of a kilogram(getit).Note:1kilo is a general notation kilo=1000.
so for the given conversion just follow the above method of cross multiplying (simply put divide by1000).

There are 1000 grams in a Kilo, so one 1g = 0.001 Kg.
So in answer to whether it would be okay to use 0.0001g instead of 1000g, it would not, because they are different amounts of grams.
If you want to convert grams to kilos, simply times by 1000, and if you want to convert kilos to grams, divide by 1000.

For the sake of Cassandra S getting her conversions correct, the following from Mish B must be corrected:
If you want to convert grams to kilos, simply times by 1000, and if you want to convert kilos to grams, divide by 1000.
This must read: " If you want to convert grams to kilograms, divide by 1000 and if you want to convert kilograms to grams, multiply by 1000"

A cm3 is the same as a mL. No conversion.
