### How to Calculate Water Cement Ratio - The Concrete Network

HOW TO CALCULATE WATER CEMENT RATIO The water to cement ratio is calculated by dividing the water in one cubic yard of the mix (in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a.50 water to cement ratio.
