This article describes how to change the unit of time (minutes, hours, days, or weeks) duration is displayed in the Duration field.
To change the unit of time displayed in the Duration field, follow thesesteps.
Use the Format Duration Macro
The Format Duration macro changes all durations for your project to thesame unit. The Format Duration macro is useful when you want to change allunit values to the same type. For example, if you have estimated durationsin hours and days, but want to display all of your durations in weeks, youcan run the Format Duration macro and change all of the durations displayedin hours and days to weeks.
If you are converting a smaller unit to a larger unit, it is possible thatrounding errors may occur. For example, if you are converting 15 minutes todays, the result is 0.03125 days. Because Microsoft Project only displaysdurations to two decimal places, it would round this result to 0.03 days.If you then converted 0.03 days back to minutes, the result would be 14.4minutes. But because Microsoft Project does not display partial minutes, itwould round the duration down to 14 minutes, instead of the original 15minutes.
To use the Format Duration macro, follow these steps:
Note: The Format_Duration macro is not included with Project 2010 and later.
On the Tools menu, point to Macro and click Macros.
In the Macro Name list, click Format_Duration.
In the Microsoft Project dialog box, type the duration unit in which you want all of the durations to be displayed: m for minutes, h for hours, d for days, or w for weeks.
Change the Units for the Project Summary Task
If the Project Summary task is displayed, the FormatDuration macro may not change the units for it. To do this, follow these steps:
