Convert mL to mg

How many mg are in mL?

[Robert Fogt]

That would depend on the density of the substance. Every substance will have a different weight to volume conversion factor.

If you know the density of the substance, or post the substance so I can try to look it up, I may be able to create the conversion.

I am not sure this is the info you need to help but I will copy it right off label...thanks for trying too!

1000mg/200ml NS(5mg/ml)
infuse continuousy at 4mg/hr

This part says there are 1000 mg of active ingredient dissolved in a total of 200 mL (or 5 mg/mL)

If dosage is supposed to be 4 mg/hr, then 4/5 (or 0.8) mL per hour. It should last for 250 hours.

There is no way to tell unless you can find some kind of "strength" statement on the bottle telling the number of mg in 1 mL, or total mg and total mL.

See the previous example. The statement of strength of the medicine was what made the calculation possible. If the bottle doesn't have such info on the bottle, you should demand it from your vet, or whoever sold you the information.

If the dog needs 500mg and the bottle is 5mg per mL, the dog would need 100ml or 100cc of the medication.

Big IF. Two different medicines are described in posts #3 and #4. I don't think we know the strength of the dog medice (#4) from the given info.

My min-pin that weighs 17.9 got stung by a bumblebee on his left back paw. My vet. said to give him 25mg. of Benadryl but I only have a measuring cup that comes with the Benadryl that is in ml. please tel me what to do. Thank you. Mae Haskins

Liquid medicines are mostly a buffer solution. There should be a statement on the bottle, package or sheet that explains how many milligrams of active ingredient there are per milliliter of the mixture. You need to find that statement and work out how many milliliters are necessary to give the 25 mg dose.
