Conversion Factor

What we have termed here as the "conversion factor" is simply a way to figure out the weight of material that must be added to one unit volume of water to give a 1 part per million (ppm) concentration. Your "unit volume" is the unit of measurement you chose to represent the volume of your water (we recommended that you use cubic feet or ft^3 for tanks and acre-feet for ponds). In the example from the previous section (volume) we chose to use gallons as our "unit volume". Using the table below (Table 2), you can identify the weight in number of grains (0.0584) or grams (0.0038) of the material needed to achieve a 1 part per million concentration in 1 gallon of water. According to the "unit volume" you chose to use, write down the weight of material needed using Table 2 and proceed to the next section.
