The amount of water required to make one pound of ice in a freezer's icemaker depends on several factors, including the type of icemaker, the ice cube size, and the efficiency of the freezer. However, as a rough estimate, it typically takes approximately 10 to 12 ounces (around 0.6 to 0.75 pounds) of water to produce one pound of ice in a standard icemaker.
Keep in mind that this estimate can vary, and it's best to consult the specific user manual or manufacturer's documentation for your freezer's icemaker to get the most accurate information regarding ice production and water consumption.
