To find out how to calculate surface acres, measure the length and width of your pond and put the measurements into this formula: You measured your pond and your pond is 250ft. long x 250ft. wide. Multiply 250 x 250 = 62,500. Divide your answer (in this case, 62,500) by 43,560. (43,560 is one surface acre). So, the math will look like this: 62,500 divided by 43,560 = 1.43 surface acres or roughly 1 1/2 surface acres is the size of your pond.
