Story points are a measurement of <em>relative</em> sizing so really there is no direct relationship with time. In order to get a measure of how much the team can achieve in a Sprint, Scrum teams will apply the principle of <a href="http://www.c2.com/cgi/wiki?YesterdaysWeather" rel="nofollow">Yesterdays Weather</a>. Mike Cohn discusses <em>Relatives Estimates</em> in much greater detail in his book "Agile Estimating and Planning" which I would strongly recommend.

So if a story is 2 story points, how long does that take. In addition, since you may have only had a couple of hours of discussion and understanding, how can you be confident in that estimate? Is there a high fidelity estimate initially then later on a low fidelity estimate? One interesting question is how to you translate story points into actually hours of estimation?

The whole idea of using Story Points is that we (humans) are better at relative sizing than we are of absolute sizing. If your Stories are small enough to estimate with some degree of confidence, then perhaps you don't need to use Story Points. You'll just have to inspect-and-adapt. Best regards, Kane. Bruce,
