This graph shows which files directly or indirectly include this file:

Functions and/or Modules
function	length_unit_name (u=length_unit_default, d=1, w=false)
	Return the name for a length unit identifier with dimension. More...

function	length (v, from=length_unit_default, to=length_unit_base, d=1)
	Convert a length value from one unit to another, with optional dimensional scaling. More...

function	length_inv (v, from=length_unit_base, to=length_unit_default, d=1)
	Recover a linear length from an area or volume value, then convert units. More...

Shorts
Convenience wrappers around length that fix the `from` unit to a named unit and the `to` unit to length_unit_base. The `d` parameter is forwarded (default 1). Use length directly when a non-default target unit or list input with d > 1 is required.
function	l_mm (v, d=1)
	Shorthand length conversion for millimeters. More...

function	l_in (v, d=1)
	Shorthand length conversion for inches. More...

Variables
	length_unit_base = "mm"

	length_unit_default = "mm"
