There is no good way .... any way you convert Hilton points to Delta miles, you lose most of the value. The Hilton site indicates you can convert 10K Hilton points into 1K Delta miles .... not a good value! I don't know any better ratio doing a straight conversion of Hilton points from your Hilton account to Delta miles in your Delta account.
However, if you have enough Hilton points for a hotel reservation/s, you probably can do better trading on Coupon Connection forum here.
You should be able to trade at 2-3 Hilton points for 1 Delta airmile; i.e. a 50-75K Hilton point reservation for a 25K Delta flight reservation, etc.
So, in a perfect world you could do two weekend rentals @$40 each and get at least 10,000 delta miles. 10,000 DL miles converted from HH points would be a staggering 100,000 Hhonors points due to there being a 10:1 ratio.

Just to put it in perspective, 10,000 Hilton points equals 1,000 Delta points. On the other hand, 5,000 AA points equals 10,000 Hilton points. So you are essentially losing 80 percent of your point value in making this swap.
Whats the best way to convert my hilton honors points into Delta skymiles?
Crazu, totally crazy thing to want to do. Not just because the conversion rate is awful, but also because Skypesos are virtually worthless once you have them. Go take a look at the Delta forum - constant complaints that the miles simply can't be redeemed at the advertised low award levels.

One can see all the possibilities using the calculator at our sister website, www.webflyer.com. Iirc, not pretty pictures due to the whopping exchange hits, unlike SPG to AA where there actually can be a bonus, or AA to Hilton HHonors.
