Question

How many ml = 1mg?

[twinmommy+2, ADN, BSN, MSN]

that depends on the drug.

[Jedrnurse, BSN, RN]

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

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

[Been there,done that, ASN, RN]

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.

Yep. Thanks. I messed up on that one.
