12mL/min * 1L/1000mL * 60min/1hr = (12*60)/1000 L/hr

1 l = 1000 ml
1 ml = 1 / 1000 = 0.001 l
12 ml = 0.012 l
1 h = 60 min
1 min = 1 / 60 h = h / 60
12 ml / 1 min =0.012 l / ( h / 60 ) =
0.012 l ∙ 60 / h = 0.72 l / h
OR
12 ml / min ∙ 60 min = 720 ml = 720 ∙ 0.001 l = 0.72 l
1 ml = 1 / 1000 = 0.001 l
12 ml = 0.012 l
1 h = 60 min
1 min = 1 / 60 h = h / 60
12 ml / 1 min =0.012 l / ( h / 60 ) =
0.012 l ∙ 60 / h = 0.72 l / h
OR
12 ml / min ∙ 60 min = 720 ml = 720 ∙ 0.001 l = 0.72 l
