Moisture regain:
It is defined as the weight of water in a material expressed a percentage of the oven dry weight of the material.

Let,

Oven dry weight of a material = D

Weight of water in this material = W

W
Moisture regain, R = …… X 100
D

Moisture content:
Moisture content is defined as the weight of water in a material express as a percentage of the total weight of the material.

W
Moisture content, C = ……….. X 100
W+D
