Only the metric system (SI - International System of Units) is scientific and legal around the world. The English system is obsolete.
SI units: kilogram, gram English units: pound-mass, slug
Mass is expressed in grams in the SI system and slugs in the English system. (these are the base units obviously multiples of these units exist. ex: kg). Volume is expressed as a cubic of any unit of length ex: M^3.
If, by 'metric system', you mean 'SI system', then the base unit for mass is the kilogram
Short answer: Metric System - grams; English system - pounds Long answer: There are two different measuring systems. One which mainly the US uses, the English units of measurements (feet, pounds, and gallons). Another is the Metric System, which the res of the world uses (meters, liters, grams). In the English system mass is measured in pounds. This is different than what people normally think of as pounds. When some on says "That weighs X pounds" they are saying it weighs the mass * acceleration due to gravity (32.17 ft/s2 ). This weight is in a unit called pound force. The Metric System is a lot easier. Mass is measured in grams, the weight would be measured in Newtons.
Mass units in the Metric system: Gram, kilogram Mass units in the English system: Poundal, Slug

...a variety of different mass units are used, depending on context, such as the slug (sl), the pound (lb)...
SI units: kilogram, gram English units: pound-mass, slug
Mass is expressed in grams in the SI system and slugs in the English system. (these are the base units obviously multiples of these units exist. ex: kg). Volume is expressed as a cubic of any unit of length ex: M^3.
For just about any type of unit, different units are used between the English system and the SI (metric) system. In both systems, there are units for length, area, volume, mass, force, temperature, etc.
The S.I units of mass is the kilogram. The International System of Units (abbreviated SI )
English units of mass include the poundmass, the poundal, and the slug.
The link will bring you to as many English units as you are likely to ever want.
