What do you want to "do" with the metric system?
The basic units of the metric system and length in meters, time in seconds and mass in kilograms. Some other units are introduced for electrical charge. Other units can be created from these using prefixes like milli-, centi- and mega- "Learning" the system has a lot to do with learning the prefixes. Physical quantities like energy, pressure and speed can be created from the mass, length and time units.
