Three metric units used to measure mass are:
Some metric units used to measure mass are gram, milligram, and kilogram. The gram is the basic unit for measuring mass. Substances that are used in small amounts, such as vitamins and medicines, are usually measured in milligrams. Kilograms are useful in measuring the mass of large objects.
The SI unit for mass is the kilogram (kg) so this is the primary metric unit for mass.
Other possibilities are:
Tonne - 1,000kg
gram (1/1,000 kg)
Less common although technically as correct as grams and tonnes are:
Gigagram (1,000,000kg)
Megagram (1,000kg)
Centigram (1/10kg)
Milligram (1/1,000,000kg)
Microgram (1/1,000,000,000kg)
technically there are 4, 4 fundamental quantities are distance mass time and electric charge (electric charge tends to be ignored
You would use kilograms (kg) to measure someone's mass in metric units.

Three metric units used to measure mass are grams (g), kilograms (kg), and metric tons (t). Grams are typically used for small, everyday items like fruit or a pencil. Kilograms are commonly used to measure larger items like a person's weight. Metric tons are used for very large quantities like shipments of goods.
The nice thing about the metric system is that there aren't three units of mass, just the one : the kilogram You can measure larger or smaller masses by changing the prefix - centigram, megagram (more commonly called the Tonne), yottagramme, zeptogram, etc.
