Question

- How do you convert Lmin^-1 to m^3 s^-1 ?

Answer 1

If by L you mean liters,
then you have 1000 cubic centimeters
a cm is 0.01 meters = 1e-2 meters and cm^3 is 1e-6 meters^3
so you have 1000 = 1e3 times 1e-6 meters^3
or
1e-3 m^3
per minute
a minute is 60 seconds
so you have
1e-3 m^3 / 60 seconds
simplifying, that is
1.667e-5 m^3/sec
or
1/60000 m^3/sec
