Instead of Dry coconut

Desiccated coconut
Use the same weight. It is drier and finer, so soak in a little warm water for 10 minutes if the recipe wants a fresh coconut texture. Slightly less creamy.
Fresh coconut
Use about 1.3 times the weight, grated. Reduce other liquid slightly. Fresher and sweeter, but more moisture.
Grated coconut
Use the same weight. If it is fresh, reduce liquid a little; if dry, soak briefly. Texture is coarser than dry coconut.
