Convert an unfamiliar measurement into a scale that you know. Be it metric, imperial, SI, or something from ye olde times, this unit converter probably has it.

Convert between different scales of:
• Temperature
• Length
• Area
• Volume
• Mass
• Time
• Speed
• Acceleration
• Flow Rate
• Force
• Energy
• Pressure
• Power
• Electric Charge

This conversion is more like an inversion, as you divide a constant by either term to get the other. The constant is 283 for Imperial gallons, so 283 / 14 L per 100km = 20.2 mpg and 283 / 20.2 mpg = 14 L per 100km. Remember the 283 cid small block Chevy? The constant for American gallons is 236.

Inch to metric system does not work

Nice Thing. But how can I convert gasoline consumption from "mpg" into "L/100 Km"?

A myriad of different units. An excellent converter, but please could you offer an option to choose color? The color clashes with my other widgets. And perhaps spice up the style of it.

DeBrazza - why don't you enter the inches in decimal format?

5/8" = .625" = 15.875mm

granted, unless you know the decimal versions of fractions off the top-o-yer-head, you would also need to open a calculator. or, you could keep a cheat sheet like this one handy:

Very nice converter!
But in bicycle mechanics - as in many other fields no doubt - SI units are not (yet) used by anglo-american writers, while dimensions are generally small; so, living on the european continent as I do, one has to convert odd expressions like 3/16", 5/8" etc. to millimeters.
I would be very grateful if your converter would accept these fractions as input.

Please?

i like this a lot. can you add pixels to the length units list?

also, i saw in another converter forum a request for bytes, MB, KB, etc. that could be helpful in preventing dumb errors in the power of ten (or thousand)...

gracias..me es muy util

ya, excellent widget. beats the proverbial socks off opera unit converter. well done, looking forward to any upgrades.

The idea and functionality of the product are amazing, but you should work more on the appearance. It's not as appealing as I wish.

yeah! now i can cheat at math!!! (iam home schooled)

By mikeoo92 , # May 18, 2007 7:51:56 PM

You obviously put some serious effort into this one- great job! Will come in very handy.

By DDFerrari , # May 14, 2007 11:04:25 AM

Just what i wanted, simple and useful. Thanks

By myrainyday , # May 12, 2007 2:26:08 AM

Thanks. I´m sometimes confused on the number of units

By reisenderpro , # May 10, 2007 11:50:25 PM

wow thanks alot scence iam home schooled i can use this lol without out paper

you just made my science school year

By mikeoo92 , # Apr 22, 2007 5:11:47 AM

Thank you, just what I need! Very useful!

Wowzerz... Nice little do-hicky it is. So many options! =D

Excellent widget! Looks great and so useful. Much better than webpage converters I used previously. I agree that if a currency converter is possible, that would make it the ultimate. Since Opera has translation features built in already, that wouldn't be necessary, IMO.

By rnrgal , # Mar 12, 2007 7:52:42 AM

As long as you write a converter for units, why not add conversion for bits, bytes, bauds, etc. In other words, all the different sizes and speeds of computer transfer? If I had the know-how to do this kind of thing, I believe that would be my first thing to add. Other than that, this is an excellent little program.

By Ottifanten , # Mar 10, 2007 6:15:37 AM

Well done, it's much better than keeping a separate calculation program.

My only criticism is that the widget always appears in the centre of the screen, which means the scrolls could go up or down. If the widget were a little larger (an invisible background at the bottom) it would make the important parts appear higher on the screen.
