I read in a previous thread that one can change the units used in PoolMath. I entered my hot tub's volume as 410 gallons based on the owner's manual, but would rather do measurements of additions with metric units - in part because measuring dry chemicals in grams and wet chemicals in mL is more precise than ounces and teaspoons, and being a small water volume a teaspoon can make a difference in chemical levels.
How does one change the units that PoolMath uses? I could reenter the volume of the tub as 1550L, but will that invalidate the entries already in place or change any of the historical data?
