The metric system has seven base units from which all other units are derived.
Length- metre m
Time- second s
Temperature- kelvin K
Mass- kilogram kg
Electric current- ampere A
Luminous intensity- candela cd
Amount of substance- mole mol.
No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.
The unit of length in the metric system is the meter (m); many derivatives are also used: kilometer, centimeter, micrometer, nanometer, etc.
The "metric system", more precisely the SI, has lots of units, depending on what you want to measure. Check the Wikipedia article on "SI units" for a list.
There are many systems. A system is a collection of units which are used together. The two commonest are the SI units, based on the metric system, and imperial units (feet, pounds etc.)
It isn't better. The customary might seem better because most Americans know the parts of the customary system they need to know and therefore it seems easy to use. 99 per cent of the world's population can't be wrong in using the modern metric system as an everyday measurement system.

The kilogram is the SI base unit of mass and is equal to the mass of the international prototype of the kilogram.In metric System there are many units to measure the mass of the objects like pounds, gm, lbs, kg,etc.

Lots, but most people use only the Metric System.
Metric system simply refers to a system of measurement in which the values are decimalized (i.e. one unit differs from another by a power of 10). The metric system commonly used in the world today is referred to by many scientists as "SI" which is short for Systeme International d'Unites, French for International System of Units.

Most sciences employ the metric system of measurement. In fact, most of the world in general uses the metric system.Technically, the standard set of units most often used is called SI units, although many of them are similar to the metric system. See the Related Questions link for all the SI units.
