The kilogram is one of the metric system's base units, and it is the mass of one liter of fresh water. The ounce, a far older and less standard unit, has its origins in the European wool trade. An ounce is 1/16 lb. The two units belong to different systems of measurement, but they both use a linear scale, so you can freely convert between them.
Multiply the weight in kilograms by 1,000, which is the number of grams in a kilogram. For example, if you are converting 5 kg then you would multiply five by 1,000. This is the weight in grams.
Divide this value by 28.3495, which is the number of grams in an ounce. So you would divide 5,000 by 28.3495 to get 176.36995.
Round your result. 176.36995 is approximately 176.4. This is the weight in ounces.
