Convert 8.2mg/mL to (micro)g/L - September 7th 2008, 12:53 PMMatt Westwood
Ooh delightful, a question in metric! That doesn't often happen round here. Full marks to the teacher.

There's 8.2 mg in every mL. There are 1000 mL in each L. So there's 1000 times as many mg in every L as there are in every mL. So multiply the 8.2 by 1000 to get the number of mg in every L.

Then there are 1000 microg in every mg. So there's 8.2 x 1000 microg in every mL. So theres 8.2 x1000 x1000 microg in every L.

Does that help? - September 7th 2008, 01:13 PMLegendsn3verdie
not really.. its hard for me to understand it without math.. this is how i do it and i m getting the way wrong answer:

(8.2mg/1ml) x (10^-3 g / 1mg) = .0082g

.0082g/1 ) x ( 1 microg / 10^-6) = 8200

i m way wrong, but u see the way i do it.. can u show me that way how u got ur answeR?? - September 7th 2008, 01:15 PMJhevon
see if either of the methods employed here can help you

one of them is doing exactly as**Matt**pointed out, but it is set out to look familiar to the method you are using - September 7th 2008, 01:19 PMLegendsn3verdie

1 mg = .001 g

1 g = 1000mcg

1 ml = .001 L

right? - September 7th 2008, 02:11 PMMatt Westwood

Convert 8.2mg/mL to (micro)g/L

write it like a grid to solve the conversion problems here.

Code:`8.2 mg |`

-------+

1 mL |

Code:`8.2 mg | 1000`

**mL**|

-------+---------+

1**mL**| 1 L |

Code:`8.2`

**mg**| 1000**mL**| 1000**(micro)g**|

-------+---------+---------------|

1**mL**| 1**L**| 1**mg**|

yes thank you every1! i got it ! ty alot.

here is what i did:

8.2mg/1mL (1mL / 10^-3 L)(10^-3 g/1 mcg)= 8.2 g/L

8.2g/L (10^6 mcg/1g) = 8.2 x 10^6

is what i did logical? i got the right answer though! - September 7th 2008, 03:50 PMJhevon
