  1. 1 L = 1000 mL
  2. × 1 g/mL (USDA FDC 174158, 1 ml = 1 g) = 1000 g
  3. = 1000000 mg

How to convert liters to milligrams

1 L = 1,000,000 mg, so multiply by 1,000,000 to go from liters to milligrams. Going the other way, 1 mg = 0.000001 L.

mg = L × 1,000,000
L = mg × 0.000001

Worked example:

5 L = 5000 mL
× 1 g/mL (USDA FDC 174158, 1 ml = 1 g) = 5000 g
= 5000000 mg
