easy calc that i can't do

Post by biology_06er » Sat Aug 11, 2007 9:15 am

Hey there,

say I have a g/L and I want to convert to ug/mL how do I do this?
I know its really simple maths but I haven't done it in ages and just want someone to explain it :oops: or see if im right

say i have 4g/L and wanna convert to ug/mL--do i just go (4/10^-6)/1000

at first i thought i have to multiply by 1000 to get L-->mL but then my answer was huge so i divided it and it seems ok...so why don't i multiply by 1000 seeing as im converting L-->mL??

Thanks in advance

firstly,

4 g = 4x10^6 micrograms

4g/L = 4x10^6 ug/L

then you must divide by 1000 (since 1mL is 0.001L)

so you end up with,

4x10^3 ug/mL (or 4000 ug/mL)
