If weight is measured in Newtons and mass is measured in Kilograms why are products in the supermarket described as having a weight in kilograms?

Answer 1

Things are like that because most people are more familiar with a kilogram, and so it makes more sense from a marketing standpoint. In general, thinking people buy less. Anything unfamiliar requires thought, and so putting it in Newtons would make people have to convert to a more familiar measurement which would make them think, which would make them worried about the future, which would make them spend less.

Besides, the differences in gravity that a person experiences at different points on the earth's surface are so small, that for most people, an object of a certain mass always has the same weight.

Answer 2

Products in the supermarket are described in kilograms because mass (measured in kilograms) is often used interchangeably with weight (force measured in Newtons) on Earth's surface where gravity is constant. In everyday situations, we tend to refer to mass in kilograms as weight since the force of gravity acting on an object is directly proportional to its mass.
