It's great! I especially like the slider part for quick calculations.

Testing out a new version.

Current version: Unit Conversion Tool

New Version: Unit Conversion Test

What do you like/dislike about each version ?

Hi MathsIsFun,

I think the newer version is elaborate and neatly presented.

Every possible detail has been incorporated.

I didn't find any error on the page.

The first version is good too; I think the information detailed in the higher version is much better.

Thanks!

hi again,

I've played with the conversions for half an hour.  The only thing I threw up was when I tried to mess around with LY, parsecs and AU along with fathoms and feet.  At this point I had 1 fathom = 6.00000002 feet.  So just a rounding error caused I suppose by the big numbers I had previously been using.  When I cleared and restarted the fathoms came out as expected, so I don't think this is a problem.  Anyone who uses a conversion factor and expects it'll be accurate at the 9th sig fig deserves what they get.

There are so many options, so I haven't done more than scratch the surface but here's what I checked:

accceleration
area
electricity (Provoked an interesting discussion with Mrs B about whether a coulomb should be on the same screen as a faraday.  So how much is one faraday she asked.  When I said 96521.9 coulombs she remembered.  Eh?  She didn't remember they measured the same thing but remembers the conversion value to 6sf.  Interesting!)
but have a look at
http://www.britannica.com/EBchecked/top … 98/faraday
energy
length
mass
power
temperature
time ( oh wow ... sidereal day!!)
velocity

All seem ok to me. 

And then I went to check degrees to radians .

Oh I'm so sorry.
