ATriple it. You might have some extra batter but its easier to deal with that than to multiply a recipe by some fraction.

This chart should help you figure out how much batter you need per pan size: http://www.wilton.com/cakes/making-cakes/baking-wedding-cake-2-inch-pans.cfm

If they are the same depth and same shape:

6" round to 9" round - multiply by 2 1/4

6" square to 9" square - multiply by 2 1/4

Different depths or different shapes = more calculations ...

This is my "calculator".  It looks at the relative areas of the pans, and assumes that the depths are all the same.  You can see that the area of a round 9" pan is 63.5 sq inches.  The area of 6" round is 28.25 sq inches.  If your recipe makes 2 6" cakes, then it is filling 56.5 sq inches.  That is just a little less than the area of the 9" round.  If you use the recipe for 2 6" rounds, it will fill a 9" round, but be a little less tall.  If you want it taller, make 1.5 or 2 times your regular recipe ( I find it hard to measure things like eggs in  smaller fractions) and make some cupcakes or 6" with any excess batter. Throw them in the freezer or give the kids a treat.  Hope that helps!
