What is the unit of measurement for mass?

Mass is a fundamental property of matter that quantifies the amount of substance in an object. The standard units of measurement for mass in the International System of Units (SI) are grams and kilograms. Grams are commonly used for lighter objects, while kilograms are used for heavier masses.

Other options are related to different physical properties. Liters and meters are units of volume and distance, respectively. Newton and Joule measure force and energy, not mass. Centimeters and milliliters indicate length and volume, respectively, but again, they do not represent mass. Therefore, grams and kilograms are the correct units for measuring mass.
