ok i really really need to know. how much is oxygen worth like per gram or per litre or any kind of measurement. measurement & price… somebody must know. a prize for being smart goes to the first person to tell me.
well, its worth a lot to me, because I’d die without it, but the consumers wouldn’t pay very much for it because its everywhere.
America was stupid to base its money system on something as rare as gold…if we were smart, we would have made money out of something more common, like air, or dirt, then everyone would be rich!!
there is a price for every element per gram, per litre etc. pure oxygen you can buy.
A scuba diver will probably know.
No they wouldn’t. Because you do not want to put pure oxygen in a tank for scuba diving. Usually just filtered compressed air is used. Though with special training you may use a mix that has about 1/3 of it being oxygen.
As opposed to the normal ~20%? Thats a big increase.
I take that back then…
Before you get a price you need to answer a few questions…
First you have to specify how you will be using the gas. There are different purities of gas available based on application: semiconductor, welding, medical, industrial process, etc.
Second you need to specify how you will be storing the gas. If you lease a cylinder from a company, they will offer different rates on filling that cylinder vs. filling a cylinder that you own. Cylinders come in many standard sizes, each size has a capacity specified in volume and pressure. There is a flat rate for the work involved in filling a cylinder, plus a graduated rate for the amount of gas put in the cylinder. One can also buy bulk gas by the kilogram, liter, cubic foot, etc., again based on the container.
If you’re looking for a quick estimate, here’s a couple numbers:
Oxygen for welding / brazing can be bought in small (16 oz.) cylinders for about $8 USD at your local hardware store (source: Bernzomatic)
A refill (again, for welding) on a leased 83 cu. ft. tank costs about $20-25 USD (source: Airgas)
Ooh!
Compressed air is fine when diving to up to 40m. Any deeper and the nitrogen levels become too high to breath compressed air to usually tri mix or other compound gases are recommended.
Just because I’m a smart arse (and a diver) I have to correct you: Many people do dive on oxygen but only at high depths.

What he said. The gas itself is free. Grab a garbage bag and wave it around. Got some! Want it compressed? Pure? Liquid? Then you’re really paying for the storage and containers, not so much for the gas itself.
What are your oxygen plans?
Free. Was I first?
wrong. you win nothing turns out price of oxygen is thirty cents per 100 grams. every element has a price, hydrogen, silver, boron, argon, magnesium, arsenic etc.
i needed it for a science project.
As a diver, I figured that I needed to clarify andycookuk’s post enough though this topic has been dead for quite awhile. I’ve been diving since the mid 1970s, so I know a bit about the sport…
By “high depth”, I assume you mean “shallow depths”. Pure oxygen tends only to be used at depths less than 20 ft due to oxygen toxicity issues.
With regards to the issue of nitrogen in your breathing air, your 40m figure is not quite accurate. Or maybe the wording of your sentence is not quite accurate. From a health standpoint, there is nothing wrong with breathing compressed air at depths greater than 40m as long as you understand that the deeper that you go, the more inebriated from the nitrogen narcosis you will get. I’ve been down to 180 ft on just compressed air. You definitely get a bit of tunnel vision / task fixation at that depth. With sufficient exposure, you can get to the point where you can still perform useful work at that depth on air, but you need to made a concerted effort to concentrate on the task at hand. Getting narced out of your head is not the most dangerous thing at extended depths on air – oxygen toxicity is more of a concern. Using the current maximum recommended PPO2 value of 1.6 ATA, around 217 ft (seawater) is the maximum that you should consider doing on air. The problem with oxygen toxicity is that you are likely to go into an ox-tox convulsion which then results in you losing your 2nd stage regulator from your mouth and your drowning soon thereafter. As such, if you are diving at greater depths, you will likely be using some sort of mixed gas diving so that the percentage of O2 in the gas is less than normal breathing air. Various gases have been used over the years as a dillutant, although mostly helium is used these days. For very extreme dives like you might see with some of the saturation diving at 1000 ft or more, hydrogen is added to the mix. For sport divers, trimix consists of oxygen, nitrogen, and helium. The narcotic effect of the nitrogen at high partial pressures helps to counteract the HPNS that helium sometimes produces.

These days, they say 1.6 ATA for the PPO2… Some of us have been around long enough that we remember when it was 1.8 ATA…

i don’t think he’ll see it/care 
Probably not… But someone else might stumble across the post while searching for something else, just like I did…
I’m not a unicyclist… I just don’t have the balance for it… I figure that at the minimum, I want two wheels on the ground…
I did have a large Ryder truck up on two wheels at one time and managed to get it back down without having an accident… Scared the 
out of me…
Besides, it might just be the response notification he needs to get back on the forum.
You never know… I periodically get response notifications on topics that I was involved in many months before on other sites because someone responded to it. There was one case recently where the topic had been dead for a year and someone responded to it and it started back up.
Of course, he might have changed his email address and thus not be getting these messages. He’s fairly young according to his profile and I suspect that kids don’t keep the same ISP or email address that much at that age. My daughter is a bit younger and she seems to always be changing her email address. Then again, sometimes I make her changer her email address because she’s registered on the wrong sites and ended up getting sold to the spammers.
That’s quite true.
How do you and your unhealthy addiction to two wheels end up on a unicycling site?
And what kind of diving do you do?
Professional or purely recreational?
I had a couple of K size helium cylinders that I was going to convert into oxygen cylinders by swapping out the valves on them. It was a weekend, so none of my local welding shops were open for me to call and I was wondering what the current price on oxygen might be. Well, a Google search turned up this topic. It didn’t help me with my question, but I saw the somewhat misinformation (or maybe just poor choice of words), so I figured I would give a bit better information in case anyone else stumbled across the topic.
Although I have made a bit of money over the years diving, I am not what would be considered a true “commercial diver”. Which means I don’t have to follow all the OSHA rules. I’m strictly recreational, but I’m not above accepting a few bucks or a case of beer after helping someone recover something they dropped overboard or whatever.
