How many mls in 5g of powder?

To convert grams of powder to milliliters, you need to know the density of the specific powder, as different powders have different densities. However, a general estimate is that 1 gram of a powder can be approximately equivalent to 1 milliliter, depending on the powder's density. Therefore, 5 grams of powder would roughly equal about 5 milliliters, but for precise measurements, you should refer to the specific density of the powder in question.
