The head of the company called their software engineers into his office and asked how long it would take to finish an upgrade. A programmer looked at the clock and estimated it would take two hours. The CEO laughed and said that the project was going to take "four, maybe five story points".
Story Points represent the effort required to put a PBI (Product Backlog Item) live. Each Story Point represents a normal distribution of time. For example,1 Story Point could represent a range of 4–12 hours, 2 Story Points 10–20 hours, and so on. This time distribution is unknown during estimation. By using reference PBI’s relative to which to estimate, it is not necessary to know how much time it takes. You just want to have a rough indication of how much time the PBI will take to complete.

Story points (SP) are used as a unit of measure in agile software development. And have been adopted as a standard unit by Scrum as well. To calculate story points, divide the total number of hours into the story’s time-boxes, then divide that number by 10,000.
Scrum also does not mandate using SP for estimation, use whatever jargon the team feels comfortable with. And then if required, move to SP estimation. (Source: www.scrum.org)
Story points, transfer points, and total points are often used interchangeably in the same instance but with different meanings for each. Story points are usually used to represent difficulty, experience needed, time investment, or time allotted for a team to complete a project.
Involving everyone (developers, designers, testers, deployers... everyone) on the team is key. Each team member brings a different perspective on the product and the work required to deliver a user story. For example, if product management wants to do something that seems simple, like support a new web browser. Development and QA need to weigh in because their experience has taught them what dragons may be lurking beneath the surface. (Source: www.atlassian.com)

The concept of Story Points is simple yet difficult to apply. Almost every Scrum team uses them, but they are not part of the official Scrum Guide. Because of this, people have different opinions on how you should use them. The term Story Point itself is already confusing, as you can use it for types of work other than User Stories. On top of that, ‘Point’ suggests a Story Point represents value. As a colleague pointed out, maybe the term ‘Planning Factor’ would help reduce the confusion many people experience. Being aware of mistakes that can be made when using Story Points helps to apply them the right way. (Source:mdalmijn.com)
Each story point is equivalent to 1 hour of work. If a project requires 100 story points, then it would require 10 hours worth of work. Another thing to keep in mind is that the hours are equivalent to story points, meaning the more story points a project requires, the more time it takes to complete the task.
Have you ever thought about using "Three Point Estimation" instead of Story Points. With this technique you get 3 estimates from at least three different developers, and you are able to calculate the standard deviation. If the standard deviation is higher than a predefined value (e.g. 10% of the weighted average) - You have to discuss it in the team and break the user story down in two or more an then reestimate. (it was the short explanation - Of course there is more to debate) (Source: www.scrum.org)
1 story point takes slightly more than an hour to complete. In general, the more complex a story point, the longer it will take. As a rule of thumb, each story point would take 2 hours, or 2 story points taken at one time would take 4 hours or 4 story points taken at two time would give you 8 hours.
