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.
The 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 MoreA 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 >Converting 385 milliliters to grams requires knowledge of the liquid being measured, but if the liquid is pure water, the conversion is 1-to-1 making 385 milliliters 385 grams.
Full Answer >Cubic meters are a unit of volume, and kilograms are a unit of mass. Cubic meters can only be converted to kilograms if the density of a substance is known. If density is known, then multiplying the number of cubic meters by the density (kg/m^3) derives the number of kilograms.
Full Answer >A cubic meter is a unit of volume, while a tonne is a unit of mass. Thus, the amount of volume required to equal 1 ton of mass depends entirely upon the density of the substance measured. For example, a cubic meter of water at roughly 4 degrees Celsius weighs 1 tonne. A tonne, also known as a metric ton, equals 1000 kilograms, or nearly 2,204 pounds.
