Pretty cool, Mark!
The other direction:
\define stones() <$macrocall $name=rpn a={{$:/temp/british-weight-converter
}} b=<<rpn 2.20462 14 / >> operation=*/>
The metric weight of
<$edit-text tiddler="$:/temp/british-weight-converter" field="text" tag=
"input" size="3"/> ''kg'' is equal to:
<$wikify name=toPounds text="<$macrocall $name=rpn a=<<stones>> b=1
operation=%/>">
<$macrocall $name=rpn a=<<stones>> b=0 precision=f/> stones <$macrocall
$name=rpn a=<<toPounds>> b=14 operation=* decimals=1/> pounds
</$wikify>
… the shortest solution that came to my mind.
Now I need a rest (i fear dreaming about African Swallows swallowing
ponies).
Good night!
