Good Website for Unit Conversions

[Lyuokdea]

I need to find a good website with unit conversions especially for high energy physics. For instance a place that has length, mass, time etc defined in terms of energy with electronvolt conversions etc.

I've been looking on the web for awhile but haven't been able to find a good one, does anybody have a suggestion?

Thanks,

Well, Google has a built-in unit converter.

For example, you can type in "1eV=", and it will give you the answer in Joules. It has loads of units built in, I've never needed to use anything else for conversions.

I don't particularly care for web site calculators and such if I can help it. The best units conversion program I have come across is free for 45 uses and has an extensive set of units built in. Plus, you can add any conversions you are missing. The program is called OmniCon and can be downloaded in a few places. iCrank is one place:

Look about half way down under the heading "Our Selections" and you'll see a link for it.

Brew: I didn't know that about Google. Damn those guys think of everything, don't they?

They do indeed, I discovered it by accident!



I forgot to say, if you ever wind up at the eng-tips.com website, don't use their units converter, or if you do be very wary about the answers it gives!

I frequent eng-tips but didn't notice a converter. That's why I like stand alones like OmniCon. You can see the conversions used if you ever have doubt.

with google you can also type things like "1 mile in centimeters" as well as "1ev=". google also acts as a basic calculator which can sometimes be better than the default windows calculator as you can write out a long calculation and then get google to evaluate it.

Can't find it now (I think I have this bookmarked in my lab computer) but there's a website that will convert quantites between units as well. For instance if you give a distance and ask to convert it to energy, it will give you (h*c)/distance.

Hey, that's a bit good isn't it!

Thanks Gokul.

I don't think google does esu/emu or any other cgs units.
