How to Calculate Moisture Content

Step 5. To arrive at the total of moisture in soil, use the following equation where soil moisture is solution C. { (A-B)/A}*100=C. In other words, subtract solution B from solution A and divide the total by solution A. Multiply the answer by 100. The total that you receive is the moisture content of the sample.
