How many MG in a gram - Office Equipment & Supplies

1 g = 1000 mg

mg is mili gram. one thousands of a gram 1/1000 gram.
so 25 mg is 25/1000 gram or 1/40 th of a gram.

See Wikipedia, for the milli, kilo, or other multipliers.

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. The conversion depends on the density of the substance.

12 ml of water weighs 12 grams or 12,000 mg. 12 ml of gold weighs about 235 grams or 235,000 mg.

mg is a measure of mass, ml is a measure of volume. There is no direct conversion between the two. A ml of water masses one gram, while a ml of gold masses over 13 grams.

The tolerance for a 1 gram weight on a Mettler PM-6000 F precision balance is 0.1 mg (0.0001 g). This means that the balance is able to accurately measure the weight of an object to within 0.1 mg of its true weight.

Hi,

Here's how to convert it.

1 milligram (mg) is equal to 0.001 gram (g). The equation is:

100 mg x 0.001 g
1 mg

So the answer is 0.1 gram (g).

Hope this helps.

There are one thousand milligrams (mg) in one gram. Thus 0.4mg / 1000 = 0.0004g
You can do the others the same way.
