UDUNITS(1) UNIDATA UTILITIES UDUNITS(1)NAMEudunits - Unidata units utility
SYNOPSISudunits [-d] [units-file]
DESCRIPTION
This utility uses the Unidata udunits(3) library to display the trans‐
formation necessary to convert from one unit to another.
units-file contains unit definitions and is used to initialize the
udunits(3) library. If not specified, then the default units-file
determined by the udunits(3) library is used.
This utility works interactively and has two modes. In one mode, both
an input and output unit specification are given, causing the utility
to print the conversion between them:
You have: inch
You want: cm
<cm> = <inch>*2.54
<cm> = <inch>/0.393701
You have: (15 lbs force/in)^2
You want: atm2
<atm2> = <(15 lbs force/in)^2>*0.995719
<atm2> = <(15 lbs force/in)^2>/1.0043
You have: celsius
You want: fahrenheit
<fahrenheit> = <celsius>*1.8 + 32
<fahrenheit> = <celsius>/0.555556 + 32
In the other mode, only an input unit specification is given. This
causes the utility to print the definition -- in standard units -- of
the input unit:
You have: fahrenheit
You want:
Definition: "0.555556 kelvin @ 255.372"
You have: geopotential meters
You want:
Definition: "9.80665 meter2 second-2"
See the manual page on the udunits(3) library for a description of the
unit-specification grammar.
OPTIONS-d Have the yacc(1)-generated parser print diagnostic messages.
The default is no messages. This only works if the parser was
compiled with the C preprocessor macro YYDEBUG defined.
DIAGNOSTICS
This package prints (hopefully) self-explanatory error-messages.
