Excel Formula

[JeffreyUtter]

Not sure if this is the correct Forum, but here goes.
I need an excel formala to convert Lat/Long coordinates to X Y State Plane California (US Feet) NAD 27, zone 0405.

Thanks.

Well, for starters it's not the right forum.  You're asking a Microsoft Excel question on an ArcGIS forum website.

Secondly, no one here is going to just write out an Excel compatible expression or macro to convert Lat/Lng to a projected coordinate system.

Lastly, since you ended up posting on an ArcGIS forum I have to ask, do you happen to have access to ArcGIS software.  If so, the process to get what you want is not all that complicated.

If you don't have ArcGIS, you can use Corpscon to do coordinate conversions. http://www.agc.army.mil/Missions/Corpscon.aspx
