How much weight goes into a 210l drum?

The weight of the contents in a 210-liter drum depends on the material being stored. For example, if the drum is filled with water, it would weigh approximately 210 kilograms, since water has a density of about 1 kg/L. However, if the drum contains a different substance, such as oil or chemicals, the weight would vary based on the density of that material. Therefore, to determine the exact weight, you need to know the density of the substance being stored.
