Even at this point, 8 decimal place accuracy looks just enough. 1 satoshi will become 10 cents USD.

One paper dollar can be responsible for one thousand dollars worth of GDP if it were to turn over three times a day (e.g., velocity of about 1,000 on an annual basis.)   The Federal Reserve says velocity for MZM is about 1.5 times per year, but M1 is nearly 7 times per year.  So if GDP is 62.9 trillion, then just under 10 trillion M1 money is needed.

<p>I think a more reliable way is to compare it to gold, since the exact value of currency in the world is very difficult to calculate. <a href="http://en.wikipedia.org/wiki/Gold" rel="noreferrer">It's estimated that 171,300 tonnes of gold have been mined in human history, which is roughly equivalent to 5.5 billion troy ounces.</a> </p>

<pre><code>5.5 billion oz/21 million bitcoin = 261.9 oz/bitcoin
</code></pre>

<p>The value of <a href="http://www.monex.com/pmr" rel="noreferrer">one ounce of gold is about $1,668</a> so the value of bitcoins in current dollars would be about:</p>

<pre><code>261.9 oz/bitcoin * 1668 USD/oz = 436,849.20 USD/bitcoin
</code></pre>

<p>If bitcoin is lucky enough (and I hope it is) to be valued at 1% of the total gold supply, then each bitcoin would be around $4,368.49. This would make the entire bitcoin supply worth about $91 billion.</p>

<p>As of 2009, we have <a href="http://goldnews.bullionvault.com/all_the_money_in_the_world_102720093" rel="nofollow">some random guy on the Internet</a> estimating $4.5 trillion as the value of all paper and coin around the world. That's a pretty decent number to use if you're looking to imagine replacing all fiat money with Bitcoin.</p>

<p>One big problem: there would be more demand for "cash" transactions since Bitcoins are more convenient than physical cash.</p>

<p>That is, due to convenience factors, a lot of us like monetary transactions that don't require the existence of any paper or coin. If we all switched to Bitcoin, how many of us would transfer BTC to a bank for the promise to pay back?</p>

<p>Anyway, $4.5 trillion divided by $21 million is $214,285.71. That said, that's in 2009 dollars with the 2009 world economy, and a lot of assumptions. Also, with a deflationary currency that is far more convenient than paper and coin, its value would likely be far greater than that if every single human being wanted to only use Bitcoin and have all financial transactions denominated in BTC.</p>

It sounds like you are asking what the value of bitcoin would be if all of the M2 money supply in the entire world had to be exchanged into bitcoins.  Of course, this is an apples to oranges comparison.
