converting whole number into thousend

[Gump123]

I have revenue in KPI 

sum({<isavi= {'Y'}>}[Total Revenue])

which get me    $4526116615.55

no i want that number to be shown as 452.6K . 

I tried auto format but not working.

[Or]

452.6K is 452600, assuming standard numeric abbreviations (K = 1000). Your number is 4,526,116,615, which is several orders of magnitude larger.
