In fact, American Express is one of the best Hilton transfer partners. If you have an AmEx card that earns Membership Rewards points, you can convert 1,000 AmEx points into 2,000 Hilton Honors points.

No, Hilton Honors points and American Express (Amex) Membership Rewards points are not the same thing, but they are connected. Amex points are a "flexible" currency earned on cards like the Amex Gold or Platinum. These points can be transferred to many different airlines and hotels, including Hilton. The standard transfer ratio is 1:2, meaning 1,000 Amex points become 2,000 Hilton points. Hilton Honors points, on the other hand, are a "fixed" currency earned through Hilton hotel stays or co-branded Amex cards (like the Hilton Aspire). These points can only be used within the Hilton ecosystem (for hotel stays, room upgrades, or experiences). Generally, 1 Amex point is valued at roughly 2.0 cents, while 1 Hilton point is valued at roughly 0.5 to 0.6 cents. Because of this, it is usually a poor financial move to transfer Amex points to Hilton unless you are just short of a major redemption, as Amex points have much higher value when transferred to airline partners for business class flights.
