To understand why 1000 grams is equivalent to 1 kilogram, it's essential to recall the relationship between grams and kilograms in the metric system. The metric system is based on powers of ten, and specifically, 1 kilogram (kg) is defined as being equal to 1000 grams (g).

Thus, when converting grams to kilograms, you divide the number of grams by 1000. Therefore:

1000 grams ÷ 1000 = 1 kilogram.

This conversion makes it clear why the answer is correct. Since 1000 grams equals 1 kilogram, it demonstrates the direct correlation between these two units of mass.
