If there is a fixed relation between story points and hours, there is absolutely no reason to use both IMO.
We have used story points as a measure for complexity/time relative to the other stories in the product backlog, not for an estimate of how long it will take to finish the story.
During the sprint planning, we estimate how long time we will spend on each story, using hours only.
Be pragmatic. Whatever works for one team may not work at all for other teams.
Also, be sure to remove such uncertainties. If the team doesn't understand what a story point means, agree on a common definition or don't use it at all.
