Apples and oranges; there's no direct/consistent ratio.

Are you maybe thinking cc's and ml's...?

There is no comparison. One is weight and the other is volume. Please talk to your instructor.

Usually it is indicated on the bottle. Morphine can be 1 mg per mL or 20 mg per mL.

In pediatrics, we weigh diapers to determine urine output. 1 mg of water (and urine) = 1 mL. That direct 1:1 only applies to water (and urine), not medications.

There are 0.25 ml per 5 mg so I believe 0.25/5mg is is 0.05ml/mg

1 GRAM of water = approximately 1 mL. 1 liter of water weighs approximately 1 kg.
