oh so like 10^3 or something

System international kinda like the metric system
Kg -- kilograms(mass)
M -- meters(distance)
N -- Newton (force)
J -- Joule (work/energy)
W -- Watt (power)
etc

SI" stands for "System International" and is the set of physical units agreed upon by international convention. The SI units are sometimes also known as MKS units, where MKS stands for "meter, kilogram, and second." In 1939, the CCE recommended the adoption of a system of units based on the meter, kilogram, second, and ampere. This proposal was approved by the Comité International des Poids et Mesures (CIPM) in 1946. Following an international inquiry by the Bureau International des Poids et Mesures (BIPM), which began in 1948, in 1954 the 10th Conférence Générale des Poids et Mesures (CGPM) approved the introduction of the ampere, kelvin, and candela as base units for electric current, thermodynamic temperature, and luminous intensity, respectively. However, the ampere is scheduled to be phased out as a base unit in the near future in favor of the ohm, which can be measured extremely accurately using the quantum Hall effect. In turn, the volt will probably replace the ohm further in the future when measurements using Josephson junctions increase in precision.
There are also tables on the site I listed below showing the different units of measurement. Hope this helps!

SI stands for The International System of Units. It's abbreviated SI from the French language name Le Système international d'unités. It's the world's most used system of units.

'SI' stands for "Intenational System' or unit of measurement. where all units for engineering, science and so forth are standardized into one international system.
since there are so many units of measurements in the world, for example the unit of pressure in SI - Mpa (mega pascal) can be converted in english unit - Psi (pound pers square inch).
not to mention that the british have their own unit of measurement and so does france.
in all 'Engineer's Handbook' you can find all unit convertion to the SI unit.
some of the most common SI units used in physics are:
Force = N (newton) = kg m/s^2
Pressure, Stress = Pa (pascal) N/m^2
Mass = kg (kilogram)
Length = M (meter)
Velocity = m/s (meter per second)
Acceleration = m/s^2 (meter per second squared)
you'll find other units in many books
physics is easy, if you'll learn to enjoy it
have a nice day !

SI stands for internationl system. but since its coming from france and stuff its backwards. don't ask me cause i'm failing physics the only reason i know that is because i cheated off a test and got that question right

I hate Physics too... I'm not taking high school physics because I hate it so much.
Anyway, it just means a unit like meter, foot, inch, etc. Just any measurement... my teacher never told us in 8th grade...
