Convert to mixed scales #19

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Thanks for this extension, pretty neat.

Feature request: I'd like to be able to convert from one measurement system 
(say, SI) to another (say, Imperial). I know I can convert single 
measurements, or a combination of measurements, into another unit - but as 
far as I can tell, it can not give me integer values, moving down the 
scale. For example:

192 cm in feet = 6.2992126 feet
192 cm in inches = 75,5905512 inches

What I'd like to see instead:
192 in imperial = 6 feet + 3.5 inches

I know this is a limitation of both Google and Wolfram... but if you could 
proxy this request somehow and split it up, you'd be my heroes.

Actually, I've been thinking about implementing something like this for a 
while. Are 
there other units combinations you can think of that might be useful?

http://gwydir.demon.co.uk/jo/units/ contains a good overview of all the various 
Imperial units - it surprised me how ridiculously complex some of these are :S. 

I'm thinking not in fixed combinations, but in 'as big as needed'. If the value 
you 
want to convert is > 1 of a particular unit, it will use that as the start, 
then take 
the remainder and move down the scale until it reaches the smallest defined.

I'd like to see Weight, Length, Volume and Area.

If something like this were going to be done, shouldn't it be by Google and/or 
Wolfram? Chromey's not going to be a simple calculator much longer if you start 
preprocessing the work you send out. :-p

Of course - but if the server doesn't do it, we could help it out a little. 
Question is, what do you want to be... a handy tool, or an interface to some 
serverside script? The way I envisioned it would be post- rather than 
preprocessing, though. You convert to "large unit" (say: 28.302 feet), then 
take the decimal part, and convert .302 feet into inches. Yes, this might 
introduce some minor rounding inaccuracy, but that still would be far more 
useful than having .302 feet :)

Down with Imperial unitary scum! Hail decimal and metric clarity!

But in seriousness: current (slow) work around is to take each decimal unit 
less than one and request it in the next smaller unit.

Like:

if you get "7.63 ft" as a result,
then send back ".63 ft in in" so you receive "7.56 inches",
then remember .56 = 56/100 so you send "reduce 56/100" so you receive "14/25",
and finally reassemble the parts manually to get "7 ft. 7 14/25 in."

Whew! Would be handy to do this automagically. I believe WolframAlpha provides 
results in multiple formats, but currently we ask Google first, then ask Wolf' 
if Google doesn't seem to work, then use Wolf's first result. Wolf' doesn't 
always "unitize" fully anyway:

<<7' 7.56">>
http://m.wolframalpha.com/input/?i=7.63+ft&x=0&y=0

Unless we can get the desired behaviour added to Google Calc or WolframAlpha, 
this might wait until we have add a math library to Chromey.

I concur with this thinking.  So if you ask for 5.65 feet in feet, inches, and 
16ths you should get 5 feet 7 inches 3/4 inches and 0.8 16ths of an inch.  

This elicits two nuances:
1. If one of the units is in fractions, does the fraction get reduced to lowest 
terms?  My example did.
2. Is the remainder expresssed as a decimal of the smallest unit?

>>I'd like to see Weight, Length, Volume and Area
Another common one would is time.
