Hello :)
How to convert microliters into micrograms??
I know it shoul be easy, but tell me how :)
Tnx

Depends what liquid you are using.

For water, one liter has a mass of one kilogram.

For other liquids, m = V\rho

Where:
m is the mass in kg
V is the volume in liters
\rho is the specific density of the liquid (water has a specific density of 1 kg/L)

Hello Gery:

Or, you can go here: onlineconversion.com

excon

I don't think that will do it excon. You need to use values that are specific to the material that is being used.
