Moles per kilogram (molal) to millimoles per kilogram
Type a value in mol/kg to get it in mmol/kg instantly.
That's 3.2× as concentrated as medical saline, while seawater, counted as salt is 1.24× more concentrated. Dissolved in water, that lowers the freezing point by about 0.93 °C (twice that for salt).
Convert the other way: mmol/kg to mol/kg
What it means
How concentrated is that?
Weight percent and grams per kilogram use the solute chosen above. The freezing-point figure is for water and a solute that does not split into ions; salt roughly doubles it.
The math
How to convert mol/kg to mmol/kg
To convert moles per kilogram (molal) to millimoles per kilogram, multiply by 1,000.
Example: 0.5 mol/kg × 1,000 = 500 mmol/kg.
In the other direction, 1 mmol/kg = 0.001 mol/kg.
Weight percent and g/kg below are for Table salt, NaCl (58.44 g/mol). Change it above and they update.
