4 mL = 0.004 LTo convert from mL to L, divide by 1000.
If you mean l as L (liters) then l is much bigger than mL (milliliter). The prefix milli means 1000 (not 1 million). So 1 L=1000 mL. So 4 L=4000 mL and 4 mL=.004L
1.29 L
2.481 L = 2,481 mL
0.0817 L = 81.7 mL
9,000 mL = 9 L
1.25 L = 1250 mL
5.03 L = 5,030 ml
398 mL = 0.398 L
102 L = 102,000 mL
26.78 mL = 0.02678 L
350 L = 350,000 mL
