Take the 2-minute tour ×  I have a function that gives me a
number of meters; how do I attach "meters" to it and send it to
WolframAlpha?  The function generating the result isn't a unit-
aware calculation or anything:  distance :=
someFunction[AstronomicalData["Mercury", "Radius"]]  The result
is about 6.07x10^15  Now I want to ask WolframAlpha[] to give me
context for that number of meters. (Show me the number converted
it to various units, show me comparisons, etc; all the stuff W|A
is great for.)  I figured I'd say something like   But no way
that I format that number into a string gives me a result that
WolframAlpha[] understands, and I can't find anything in the
manual explaining a better way to format it.  I've tried the
Quantity[] function, and all kinds of variations on  x :=
NumberForm[N[distance], 10] WolframAlpha[ToString[x] <>
"meters"]  But it just interprets it as "15x6.068x10 meters"
I've tried Googling every variation on "format a number to send
to the wolframalpha function" and found nothing
