      "q": "Why multiply by 7.48?",
      "a": "That's the standard conversion factor for gallons per cubic foot of water (there are exactly 7.48052 gallons in one cubic foot), which converts your volume calculation from cubic feet into the gallons pool chemical dosing charts use."

      "q": "Why do I need to know my pool's gallon count?",
      "a": "Chlorine, shock, and other pool chemical dosing instructions are almost always given per 10,000 gallons, so accurate volume is essential to avoid under- or over-treating your water."
