Its called RRP ( Recommended Retail Price) . Every company/corporations does this. Similiar to Samsung,Apple,LG,etc . They have their own pricing scheme and consumer cant expect a simply conversion.

And to be honest, A device that can play 4k 60 FPS with ray tracing etc at RM3850 is cheaper compared to a PC. A graphic card alone will cost more than half of PS5 Pro price.
