From GameWatcher: “Elite: Dangerous, Frontier Developments’ space sim, plans to revamp its Frontier Points in the upcoming September update. Previously only available on consoles, they will change their name to Arx Points and also make their way over to PC.
The developer detailed the exact Arx Points pricing in a forum post, while also explaining what will happen to remaining Frontier Points. Should you still have some in your account after the September Update goes live, they will automatically get converted to Arx Points (1 Frontier Point = 20 ARX) the first time you hop into Elite: Dangerous following the update.”
