SI is an international standard system of units. Most people would call it the metric system. SI has standards for the kilogram and meter that can be referenced, to make and calibrate measuring devices.
System International
Specially includes four more units of electric current, temperature, light luminosity, amount of substance
Includes two supplementary. One for plane angle and the other for solid angle.
So consistent.
Somehow an evolved system
SI Units are based on the metric system

Base units
SI units: kilogram, gram English units: pound-mass, slug
It is the International Standard of units.
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.
Inches, feet, miles, and pounds are some units that are not part of the SI.

some SI units: length = metres time = seconds mass = kilograms electric current = amperes temperature = kelvin
SI is the Systeme Internalionale of measurement in which the Metre, kilogram and Second are some primary units. An older system based on metric units used centimetre, gram, and second as the primary units. Obviously these may be converted into SI units, but the CGS system is no longer used. [Some of the definitions of the fundamental units differ between these systems.]
Quantity English Units Equals SI Units force lb = 4.4482 N mass Slug = 14.5938 kg length ft = 0.3048m Not really a good specified question but here are some of the more common basic English units converted to si units
SI and metric are the same units.
International System of Units (SI)
Everything. There is seven base units: metre, kilogram, second, ampere, kelvin, candela and mole. From these seven base units, several other units are derived. In addition to the SI units, there is also a set of non-SI units accepted for use with SI which includes some commonly used units such as the litre.
In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.In the SI, energy is measured in Joules.Some other units (not part of the SI) include: erg; BTU; calores; and others.
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
