Unofficial SI units are units of measurement that are not part of the International System of Units (SI) but are commonly used in practice. These may include units like the "bar" for pressure, "liter" for volume, and "angstrom" for length. While they are widely recognized and used in various fields, they lack formal acceptance by the SI standards. Their usage often persists due to convenience or tradition in specific industries or disciplines.

International System of Units (SI)
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.

SI units are more accurate than English system units
When SI units combine, they create derived SI units that are used to express physical quantities. These derived units are formed by multiplying or dividing the base SI units. Examples include the Newton (kg*m/s^2) for force and the Pascal (N/m^2) for pressure.
Si and metric are the same thing. SI was a redefinition of metric in 1960.
"SI", from the French "Systeme Internationale".
The SI has 7 base units. These units can be combined in an almost unlimited way to form other (derived) units. The Wikipedia article on "SI derived units" lists some examples.
