There are 1000 mL in 1 L. To convert from L to mL, you multiply the given value by 1000.
E.g. 7 L x 1000 = 7000 mL
340 L = 340000 mL
1 L = 1000 ml
0.09 L
1.29 L
divide by 1000
ml
2.56 L is 2,560 mL
4232 ml = 4.23200 L
Depends on the size Plant pot - 3 L
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
9,000 mL = 9 L
no 1000 ml = 1 l
