Because the milliliter is a unit of volume, and grams are a unit of mass, the answer to this question depends on what material one is measuring. For one of the most common materials, water, the conversion is simple. Because 1 milliliter of water equals 1 gram of mass, 300 milliliters of water weighs 300 grams.
Know MoreThe answer becomes more complicated if measuring a volume of a less common liquid. For example, the heaviest liquid at room temperature, mercury, has a mass of 13.6 grams per milliliter. In turn, 300 milliliters of mercury has a mass of 4,080 grams, which is a bit more than the weight of two 2-liter bottles of soda.
Learn more in MeasurementsIn order to convert milligrams to milliliters, one must know the density of the substance; if the density is measured in milligrams per milliliter, the milligrams of mass of the object being measured are divided by the density of the substance to determine the volume in millimeters. Because density is generally not listed in milligrams per milliliter, it is likely that some calculations must be done to convert the density into the appropriate units.
Full Answer >A weight of 300 grams is equal to roughly 0.66 pounds. One can convert grams to pounds by multiplying by a conversion factor of 0.00220462.
Full Answer >If converting milliliters to grams of pure water, the relationship is one-to-one, so 120 milliliters of pure water is equal to 120 grams. However, when converting any other substance, density must be taken into account when completing the conversion.
Full Answer >To convert 80 grams of a substance into milliliters, one must first know the density of the substance. Grams are units of mass, while milliliters are units of volume.
