The answer is in the prefixes.
m or milli is 1x10^-3
ì or micro is 1x10^-6
p or pico is 1x10^-9
n or nano is 1x10^12
Now, the mole is a value relating to 6.022x10^23 units of anything. one mole of flowers is 6.022x1023 flowers. One mole of Oxygen is 6.022x10^23 molecules of oxygen.
So....
One mM or millimole is 1x10^-3 x 6.022e^23 = 6.022x10^20 items.
likewise, one ìM is 6.022x10^17 items, one pM is 6.022x10^14 items, and one nM is 6.022x10^11 items. In each case, multiply the value of the prefix times the unit to get the final numerical result.
By the same token, if I have one mole, and want to know how may millimoles or micro moles that is, then:
1 mole x 1,000 mM/M = 1,000 mM
1 mole x 1,000,000 ìM/M = 1,000,000 ìM
1 mole x 1,000,000,000 pM/M = 1,000,000,000 pM
and so forth.
Finally, if I want to move from one mM to on pM, then:
1 mM x 1,000 pM/mM = 1,000 pM
