The video tutorial explains the differences between mass and weight, emphasizing that mass is the amount of matter in an object, while weight is the force of gravity on it. It introduces the metric system units for measuring mass: grams for small objects, kilograms for larger ones, and metric tons for very heavy items. Milligrams are used for tiny measurements, such as in pharmaceuticals. The tutorial highlights the simplicity and efficiency of the metric system, which is based on powers of ten, making calculations straightforward. It concludes with a review and questions to reinforce learning.
