agile estimation Questions

Hi everyone,

I have just taken over responsibility as a a scrum master and although i have worked under a scrum team before for a year but i always had difficulty in estimating according to story points. So in my first prokject as a scrum master, I took a risk and though to map story points against hours and it went very well. Here is how i mapped:

Points - Hours

1       2-4

3       4-8

5       8-16

7      16-24

9      24+

When i gave them a range the team was very comfortable so what i did estimated it according to the table above and in the end they all had a rough time frame then when and how they are going to complete it. I need to know that if it is feasible in long run?

Need very valuable comments on this one :)
