How to Calculate a Weight-to-Strength Ratio Sciencing A low weight-to-strength ratio is not only desirable in the gym. The weight-to-strength ratio, when descriptive of a material, relates the density of the material to its ability to withstand permanent deformation or fracture under pressure. Low-ratio values indicate that the
