Get Mailbox Database Size in GB Exchange 2010 Powershell Command

I presently get my Exchange database statistics using the following command:

Get-MailboxDatabase -Status | Select-Object Name,DatabaseSize,AvailableNewMailboxSpace | Sort-Object Name | fl

Now that my database are over 1TB in size, and I provide my reports in GB, I have to manually convert the TB to GB (in this case I use Google)

Is there a way to have the output on the DatabaseSize ONLY, given in GB.

I do not want the AvailableNewMailboxSpace output modified, as it does a good job providing it in either GB or MB, depending on the size.

Thank you.

Simple method is to create a custom property..

@{N="DatabaseSize GB";E={$_.DatabaseSize.ToGB()}}


For example..
Get-MailboxDatabase -Status | Select-Object Name,@{N="DatabaseSize GB";E={$_.DatabaseSize.ToGB()}},AvailableNewMailboxSpace | Sort-Object Name | fl

These are the 2 commands I usually use:

To GB: get-mailbox | Get-MailboxStatistics | Select-Object DisplayName, {$_.TotalItemSize.Value.ToGB()}, DatabaseName | export-csv U:\mbreport.csv

To MB: get-mailbox | Get-MailboxStatistics | Select-Object DisplayName, {$_.TotalItemSize.Value.ToMB()}, DatabaseName | export-csv U:\mbreport.csv

For more details, I use this:

get-mailbox | Get-MailboxStatistics | Select-Object DisplayName, {$_.TotalItemSize.Value.ToMB()}, ItemCount, DatabaseName | export-csv C:\mbreportmb.csv

Hope it helps,

Subsun, your report is what i'm looking for:

-Is there any way to have the Gb results to 2 decimal places? Such as: 1220.35
-Is there any way to have the result include the 'GB', as it just displays the number now, can we have the 'GB' appended to the result (only because it adds an extra step for me to do)

Thanks!

Try..
Get-MailboxDatabase -Status | Select-Object Name,@{N="DatabaseSize GB";E={"$([math]::round($_.DatabaseSize.Tobytes() /1Gb, 2)) GB"}},AvailableNewMailboxSpace | Sort-Object Name | fl
