Is a 50g pot of cream the same as 50ml?

A 50g pot of cream is not necessarily the same as 50ml, as grams measure weight while milliliters measure volume. The conversion between the two depends on the density of the cream. Generally, cream has a density close to 1g/ml, so 50g of cream would roughly equal 50ml, but this can vary slightly based on the specific cream's fat content and other factors.
