Ado Badr,

You could have used google or wikipedia to find out. If you scan the CR4 FAQ (frequently asked questions) you'd find this:

Look for answers before you post. Check a search engine or two to see if you can find the answer to your question or a collection of useful links. If it's not or if the answer is unclear, then that's a pretty good justification for asking the question. This is not to stifle questions, but you're less likely to be insulted if you have done a little research ahead of time.

So, my suggestion is you type "bar" or "pressure units" in Google, or other search engine, or go to wikipedia, or similar, and do some research. If you need more clarification, then you can come back here and ask your question.

I apologize if I sound rude but you learn better if you search for the answers yourself and ask for help only if you cannot get the information you need.

Dear Friends

Thank you for your help, and it was just a beginning

Regards

Bara
also called Ibara, Malagasy people who live in south-central Madagascar and speak a dialect of Malagasy, a West Austronesian language.

Traditionally a bellicose people, the Bara lived in a great many independent groups based on lineage identity. Five main kinship groups exist, and formerly the Bara had two kingdoms, one of which survived until it was disbanded by the French. -- Encyclopedia Britannica

Barg
Nothing found. Probabable misspelling of "barge":

Main Entry: ¹barge
Pronunciation: 'bärj
Function: noun
Etymology: Middle English, from Anglo-French, from Late Latin barca
: any of various boats: as a : a roomy usually flat-bottomed boat used chiefly for the transport of goods on inland waterways and usually propelled by towing b : a large motorboat supplied to the flag officer of a flagship c : a roomy pleasure boat; especially : a boat of state elegantly furnished and decorated.

So one is a group of indigenous people of Madagascar, the other is a type of boat.

Ask a silly question, get a silly answer!

The same as studying physics, and not doing so.

Bara - A place in Peshawar(Pakistan) known as no man's territory where the pathans (can be peshawari or afghani or both residents) sell smuggled goods. The Pakistani Govt., has no say to this. Here you can get all guns & ammination,rocket launchers,kleshnokofs(or however the shit you spell them).If you're ever kidnapped and taken here then no one can recover you not even the Govt., unless their tribal leader agrees.Funny it is a part of Pakistan yet there is a border. You might find Osama here qand collect the ransom and become a rich man.

Barg - ditto as STL Engineer
