I Know...I Am Such An Idiot For Posting So Many On One Subject.
But Heres The Thing:::
0.2 mg = ? g
..Searched it and it came up 0.0002,Anybody know another way to find the question out?..
8.6 kg = ? g
..Searched it and it came up 0.0086,Know a different way?..
800 g = ? mg
..Came up 800 000,Another way?..
1.7 kg = ? g
..Came up 1700,another way?..
One kilogram has 1000 grams.
So to convert from grams to kilograms, divide by 1000.
Same goes between grams and milligrams.
To convert milligrams to grams, divide by 1000.
So just divide all by 1000?
Dr. Bob has posted a rule that you can easily follow to know if you should divide or multiply, and also how much to divide/multiply.
In the case of the present converions, you go up the table three lines, so you divide by 1000. Other cases may differ. Follow his rules, which I take the liberty to reproduce below:

"Here is a mnemonic to help with metric conversions.
kilo
hecto
deka
gram(or other unit)
deci
centi
milli
You need two rules to use the table. Going down the table move the decimal point to the right. Going up the table move the decimal point to the left.
1.2 kg to grams. Move down 1 to hecto, a second to deka, and a third to gram. So we move the decimal point three places to the right.
1.2 kg = 1200 grams.
4,000 mg to grams.
Start at milli, move 1 place to centi, a second to deci and a third to gram.
4,000 mg = 4.000 g"
To convert units from one metric prefix to another, you need to multiply or divide by the appropriate conversion factor. Here are the steps to solve each of the conversions mentioned:
1. 0.2 mg to g:
The prefix "m" stands for milli, which means 0.001. To convert milligrams (mg) to grams (g), you need to divide by 1000. So, to convert 0.2 mg to g, you can calculate as follows:
0.2 mg ÷ 1000 = 0.0002 g
2. 8.6 kg to g:
The prefix "k" stands for kilo, which means 1000. To convert kilograms (kg) to grams (g), you need to multiply by 1000. So, to convert 8.6 kg to g, the calculation is as follows:
8.6 kg × 1000 = 8600 g
3. 800 g to mg:
The prefix "g" stands for gram, which means 1. To convert grams (g) to milligrams (mg), you need to multiply by 1000. So, to convert 800 g to mg, you can calculate as follows:
800 g × 1000 = 800,000 mg
4. 1.7 kg to g:
To convert kilograms (kg) to grams (g), you need to multiply by 1000. So, to convert 1.7 kg to g, the calculation is as follows:
1.7 kg × 1000 = 1700 g
These are the standard conversion factors for these metric units. Using these conversion factors, you can easily convert between different metric prefixes.
