As we know One Gm/L is equal to 1000 Mm/L (1 Gm/L = 1000 Mm/L).

To convert Gigameter/liter to Megameter/liter, multiply your Gm/L figure by 1000.

Example : convert 25 Gm/L to Mm/L:

25 Gm/L = 25 × 1000 Mm/L = Mm/L

To convert Megameter/liter to Gigameter/liter, divide your Mm/L figure by 1000.

Example : convert 25 Mm/L to Gm/L:

25 Mm/L = 25 ÷ 1000 Gm/L = Gm/L
