Duration Conversion and Calculation

[Tevon713]

I have incident time stamp column, attempted to convert to duration. It giving the "Expression.Error: We couldn't parse the Duration literal."

Searched and found in the community, it now returning "null" for those not having days in custom column. How to correctly format and then take average of this column to display in d:h:m:s ?

Hi @Tevon713 ,

Here are the steps you can follow：

1. Create calculated column.

Convert Time to Second：

seconds =
var _day=VALUE(left('Table'[Incident Duratio:create-resolve],2))
var _hour=VALUE(MID('Table'[Incident Duratio:create-resolve],4,2))
var _minute=VALUE(MID('Table'[Incident Duratio:create-resolve],7,2))
var _second=VALUE(RIGHT('Table'[Incident Duratio:create-resolve],2))
return
_day * 24 * 60* 60
+
_hour * 60 * 60
+
_minute * 60
+
_second

average time：

Duration Average =
RIGHT ( "0" & INT ( AVERAGEA ( 'Table'[seconds] ) / ( 24 * 60 * 60 ) ), 2 ) & ":"
    & RIGHT (
        "0"
            & INT (
                (
                    AVERAGEA ( 'Table'[seconds] )
                        - INT ( AVERAGEA ( 'Table'[seconds] ) / ( 24 * 60 * 60 ) ) * ( 24 * 60 * 60 )
                ) / 3600
            ),
        2
    ) & ":"
    & RIGHT (
        "0"
            & INT (
                (
                    AVERAGEA ( 'Table'[seconds] )
                        - INT ( AVERAGEA ( 'Table'[seconds] ) / 3600 ) * 3600
                ) / 60
            ),
        2
    ) & ":"
    & RIGHT (
        "0"
            & (
                AVERAGEA ( 'Table'[seconds] )
                    - INT ( AVERAGEA ( 'Table'[seconds] ) / 60 ) * 60
            ),
        2
    )

2. Result:

Thank you @v-yangliu-msft.

I'm getting this error, tried converting column various format. Attached link to pbix here.

Another quick question: If I wanted to calculate the average of all numbers that belongs to a certain category. I'm thinking something along the line of the follow...

Average Number of Category=
Calculate('Table'[Duration Average],Filter(Table, 'Table'[ColumnName]="XYZ"))
