In this chapter, information is usually presented in the System International des Unites, called in
English the International System of Units and abbreviated SI. Various tables of conversion factors
from other unit systems into the SI system and vice versa are available. The following table is only
intended to enable rapid conversion to be made with moderate, that is, five significant figure, accuracy,
usually acceptable in most engineering calculations. The references listed should be consulted for
more exact conversions and defintions. |
