How to convert ppm

[Reefnut2010]

For those better at math than myself... How do you convert 150ppm into mg/hr ?

 

[Reefnut2010]

Figured it out. Rather simple...it = 150 mg/hr

what are you talking about? obviously ppm and mg/hr are not measurements of the same thing, and are not directly convertible without some other context which you have not provided.

FWIW, 150 ppm = 150 mg/kg, which in seawater is about 154 mg/L (since seawater weighs a bit over 1 kg per L).

Maybe that will help with whatever calculation you are trying to do.

ppm is a measurement of concentration whereas mg/hr is a measurement of rate. they cannot be converted from one to the other as they do not have compatible units. ppm has no unit of time.

Thank you Randy. That helps even more.
