What size can do I need for 400 grams of coconut milk?

To measure out 400 grams of coconut milk, you will need a container that can hold at least 400 milliliters, since the density of coconut milk is approximately similar to water (1 gram per milliliter). A standard measuring cup, which typically holds 240 milliliters, would not be sufficient, so you could use a larger measuring cup or a kitchen scale for accuracy. A 500-milliliter container would be ideal to comfortably accommodate 400 grams of coconut milk.
