Write an expression that converts 50 liters per minute into milliliters per second
Mariulka [41]
So to convert from leiters per minute to milileters per second

lieters=L
milileters=ml
minute=M
second=S

L/M=liters pre minute
ml/s=milileters per second

so to convert, just conver them seperately first

L=1000ml
M=60S
therefor
conversion factor for M to S=
M times 60S/1M=minutes


conversion factor from L to ml=
L times 1000ml/L


so basically to convert, just multiply the equations gotether

L/M times 1000ml/L times M/60s (we flipped the M to S equation since M is on the bottom)    =L/M times 1000/60=L/M times 100/6=L/M times 50/3

if you have 50 liters per minute than
50/1 times 50/3=2500/3=833.33333 ml per second
