Millimolar to milliosmoles per liter
Type a value in mM to get it in mOsm/L instantly.
150mOsm/L
That's about the same as a hypotonic solution. That is hypotonic: cells placed in it would swell.
Convert the other way: mOsm/L to mM
What it means
How concentrated is that?
Real salts do not dissociate perfectly, so measured osmolarity runs a few percent below the ideal figure. The osmotic coefficient of saline is about 0.93.
The math
How to convert mM to mOsm/L
Osmosis counts particles: mOsm/L = mmol/L × particles per molecule. The figures below use the solute selected above.
Example: 150 mM = 150 mOsm/L.
The table below is for Glucose (1 particle).

About these units
Millimolar (mM)
Millimoles per liter, before counting the particles each one splits into.
Milliosmoles per liter (mOsm/L)
The clinical standard. Plasma is about 290 of them.
