\ cora.fs -- Coraphyco COnversion RAtios and PHYsical COnstants in Forth

\ Version 1.1

|

|
|

|
\ Coraphyco provides a Forth environment to facilitate conversion of
|
||
|
\ quantities among a large variety of measurement units and systems.
|
||
|
\ Inspired by Frink by Allan Eliasen.
|
||
|
\ This version is a simple implementation providing Forth constants
|
||
|
\ for conversion and physical quantities and a few words to simplify
|
||
|
\ display and conversion.
