Actually those are two different things – one is the pressure and the other the flow. You never need to convert one to the other.
For example, a Bethlehem Bravo's requirement for maximum performance is 8 psi; 66 cu. ft./hr. (1867 l/hr.) so 8 psi pressure and 31 lpm (litre per minute)

And the Alpha 8 psi; 27 cu. ft./hr. (765 l/hr.) – 13 lpm
