Roger is curious to know the total weight of all four sandwich fillings he bought.

He weighs the fillings twice, once using ounces and once using grams. If 16
ounces = 1 pound and 1,000 grams = 1 kilogram, will the total weight of the
sandwich fillings be a greater number of ounces or a greater number of grams?
Explain your answer.

The total weight of the sandwich fillings will be a greater number of grams.

To determine this, we need to compare the conversion factors given. We know that 16 ounces equals 1 pound and 1,000 grams equals 1 kilogram. Since there are more grams in a kilogram than the number of ounces in a pound, it follows that the total weight in grams will be greater.

Additionally, when comparing the two weight measurements, it is important to note that grams are based on the metric system, which is an international standard. Ounces, on the other hand, are primarily used in the United States and a few other countries. The metric system is widely recognized and used globally, making grams a more universally understood and accepted unit of measurement.
