The main reason for reporting the Matthews coefficient might be historical, i.e. old fogeys are familiar with the numbers because that's the first way the cell content was reported. People might have been reluctant to report the solvent content in the old days because it requires making some as

Hello, why do people and programs (like phaser) use the Matthews coefficient instead of percentage of solvent content? The amount of information seems the same to me and the coefficient is very cumbersome, whereas a percentage is obvious and it's easy to imagine what it means. Thanks for the disc
