When entering time estimates, we always use hours. And in all our correspondence with the customers, we also refer to estimates in hours.

It's annoying that JIRA converts the estimates to days, weeks and so on according to the conversion rule that must be entered. My rule says, that a working day is 6 hous. When giving an estimate of 10 hours, JIRA converts this to 1 dag and 4 hours.

Is there a way to avoid this conversion so that the estimate always is shown in hours? If not i would like to request this feature.
