Solder requirements in this table are based on estimate of weight of solder used to prepare
100 solder joints of sizes shown.
Two (2) ounces (0.06 kg) of solder flux will be required for each pound (0.45 kg) of solder.
U.S. customary units in this document are the standard; the metric units are provided for
