si.7
|
||||
----
|
||||
|
||||
A reference for the SI units. Includes
|
||||
|
||||
* Values of prefixes
|
||||
* All base and derived units with names from the SI brochure
|
||||
* All accepted non-SI units
|
||||
* Conversions between some non-SI units and SI equivalents

How to Install
|
||||
==============
|
||||
|
||||
Place into your system's manual page directory (on most systems, this
|
||||
will be `/usr/local/share/man/man7`), and run `makewhatis` as root.
