Final answer:
The quantity that you would measure in kilograms is mass.
Step-by-step explanation:
The quantity that you would measure in kilograms is mass.
The kilogram is the SI unit for mass. It is a measure of the amount of matter that an object contains. For example, if you wanted to measure the mass of a watermelon, you would measure it in kilograms.
It's important to note that mass is different from weight. Mass is a measure of the amount of matter, while weight is a measure of the force of gravity acting on an object.
