NOTE
When handling units, be extremely careful not to use
different systems of units. For example, the weight of
an object should be expressed in [kg] in the SI
system of units because it is handled as "mass" or
[kgf] in the gravitational system of units because it is
handled as "force." Inertia is expressed in [kg⋅m
2
] in
the SI system of units or in [kgf⋅cm⋅sec
2
] in the
gravitational system of units.
In this manual, both systems of units are written
together to support them.
