The Centimeter-Gram-Second (CGS) System of Units
Description
Examples
The CGS system of units has the centimeter, gram, and second as its base units. Although the default CGS system does not include units of electricity or magnetism, the electrostatic and electromagnetic systems, which are also based in the centimeter, gram, and second, do.
When used in conjunction with the UseSystem command, the CGS system sets the following units for the given dimensions.
Dimension Name
Unit Name
length
centimeter
mass
gram
time
second
speed
kyne
acceleration
gal
force
dyne
energy
erg
power
erg/second
pressure
barye
plane angle
radian
solid angle
steradian
Notes:
To enter a unit in 2-D Math input, select the unit from the appropriate Units palette. If the unit you want is not there, select $\mathrm{unit}$ and then enter the unit.
When you edit a unit, double brackets appear around it.
