Whats more a mg. or a ml. - Texas Instruments TI-84 Plus Calculator

For water, 1 Liter (volume) has a mass of 1Kg.
milli (m) is "1/1000 of".
Kilo (K) is "1000 times".
So:

Mass: Volume:
1Kg = 1Lt
1 000g = 1 000ml
1 000 000 mg = 1 000 ml
1 000 mg = 1 ml
400 mg = 0.4 ml

Depending on what liquid you are weighing, the density / mass can vary.

If inkjet, I guess it will be similar to H2O.

If it sinks in water, it is denser.
If it floats on top, it's less dense.

You are mixing millilitres (Volume) with (Milligrams) Weight. For that you have to assume that 1,000 milligram is equal with 1 millilitre, but that only works with distilled water, which is also 1 cubic centimetre.

1,000 milligrams Therefore, there must be 1,000 milligrams in a milliliter, making the formula for mg to ml conversion: mL = mg / 1000 .Dec 21, 2021

ML 63 Pill levofloxacin 500 mg

For that product 1mL weighs 1 mg. 1 for 1.
750 mg over 6 hours is equivalent to 750 mL over 6 hours.
In mL per minute, you calculate 750 mL / (6*60) m = 25/12 mL/min
Now just find out of may mL are in a drop. Divide the result above by the number of mL/min and you get your result in drops /min
I assumed that gtts stands for drops (in French gouttes) per minute.

Hmm injection eh?

Well, 80 mg is not 80 ml, nowhere near.

For pure water 1 ml is 1 gram. So 80 ml is going to be 80 g which is 80 000 mg. This all comes form the base relation 1 litre (1000 ml) is 1 kg (1000 g).

For other substances, it will be a bit more or less than 1 gram in a ml, but not much.

It would help us both to know what is the injection, we are not the police.

A Milligram is MG and a Milliliter is a ML. (MG) is used in dry measure and (ML) is used in liquid measure

1000 micrograms (mcg) EQUALS 1 milligram (mg)
1000 milligrams (mg) EQUALS 1 gram (g)
1000 grams (g) EQUALS 1 kilogram (kg)

1 kilogram (kg) EQUALS 2.2046 pounds
1 ounce EQUALS 28.35 grams
1 pound EQUALS 0.4536 kilograms
1 pound EQUALS 16 ounces
16 ounces EQUALS 453.6 grams

1000 milliliters (mL) EQUALS 1 liter (L)
1 liter (L) EQUALS 1.0567 quarts liquid
1 quart liquid EQUALS 0.9463 liter
4 quarts EQUALS 1 gallon

Milligram is a unit of mass (or weight), milliliter is a unit of volume. Any conversion between them depends on the density.

62.5 milligrams of water occupies 62.5 milliliters. 62.5 milligrams of gold occupies about 3.2 milliliters.

Milliliter is a unit of volume, milligram is a unit of mass (or weight). There is no direct conversion between them.

5 mg of water occupies 5 ml. 5 mg of gold occupies about about a quarter of a ml.

That depends on what you have. One mg of water occupies one ml. One mg of lead occupies less than a tenth of a ml.

mg is a unit of mass, ml is a unit of volume. There is no conversion between them. A mg of water occupies about a ml, a mg of lead takes up a lot less space.
