The equation is in the name: you simply divide the weight of water by the total weight of cementitious material. What ratio you target depends on what you want from the mix. Typically, high strength mixes (6,000-to-10,000 psi) have a low w/c ratio such as 0.38 and lower strength mixes (5,000 psi) may have a ratio of up to 0.45.
