Grams are a measurement of weight, millilitres are a meaurement of volume.
The standard for the metric volume (put in lamens terms) of the litre is the amount of space taken up by one kilogram in weight of pure water therefore the volume taken up by 300 millilitres of pure water will weigh 300 grams. That is of course if you are measuring 300 grams of pure water, if you have 300 grams of an item that has a different mass and density to pure water you will then have that item taking up a different amount of volume. This difference in volume can be quite dramatic depending on the density and mass of the item.
0.3 mils.
300g = 0.3kg
300 grams
300 ounces of water is 8,504.858 ml
There are 140 grams, or about 4.938 ounces.
There are 453.59237 grams in one pound. Therefore to get amount of pounds in grams, value in grams has to be divided by amount of grams in one pound:300 grams = [grams] / 453.59237 = 300 / 453.59237 = 0.6614 pounds300 grams is about 0.66 pounds.
300 grams is equal to 0.66 pounds.
One micro-gram (µg) equals to 0.001 milli-grams (mg). 300 µg = 0.3 mg
You're probably wondering because of alcohol, so 3000 ml would be about 100 shots.
200 grams is equivalent to 7 dry ounces, but I don't know of a conversion for grams to fluid measurements.
300 grams = 0.66 pounds
300 grams is about 11 ounces.
