Why aren't liquids measured in grams?

They could be. But liquids change shape to fill whatever container they're placed in. This makes measuring them by volume easy. In fact, since liquids have to be kept in containers, it almost makes measuring liquids by volume necessary. read more

In fact, since liquids have to be kept in containers, it almost makes measuring liquids by volume necessary. In contrast, it's very difficult to measure solids by volume. read more

Liquids can be measured by weight and volume. As liquids have different densities , measurement by weight, say a kg of two different liquids with diffrent densities will vary in the amount weighed. If measured by volume, the liquids are filled upto the graduated level and liquids will be of the same quantity irrespective of their densities. read more

any type of liquid could be measured in terms of grams, because a gram is a measurement of weight. read more
