This is not a proper conversion. Milliliters (mL or ml) and liters (L) are measures of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
3 litres (30 centilitres)
1 l is equal to 1000 ml. 1.8l is equal to 1800 ml.
That is approximately 227 ml
300 grams of water is 300 ml.
This is not a valid conversion. Milliliters (mL or ml) and liters (L) are measures of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
Assuming a density of 1g/ml, 1,000,000mg
There's no single answer to that, as ml is volume and mg is weight. Depending on the density of the substance the answer will be different.
11/5 mL 1.2 mL
One milliliter is equal to one gram (1 mL= 1 g), and there are 1,000 milligrams in a liter, so 3 mL is equal to 3,000 milligrams and 100 mg is equal to .1 mL.
Milligrams and milliliters are two different measures, milligrams measure mass and milliliters measure volume and you can not convert one to the other.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
Does not convert; milligrams (mg) and grams are measures of weight or mass and mL (milliliters) is a measure of volume.
Milligrams and milliliters measure different things (milligrams measure mass and milliliters measure volume), so there is no universal conversion factor. For example, 300 mg of air takes up about 250 ml, whereas 300 mg of water takes up only 0.3 ml. To get an answer you need to specify what substance you are measuring, or, if the substance is in solution, you need to specify the concentration of the solution.
