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.

Not sure what you mean with "light build". The SI (metric) unit for mass is the kilogram. For small objects, smaller units such as grams and milligrams can be used; for larger objects, the ton (= 1000 kilograms) is also used.
