Is there any way for one to calculate the correct/ideal/recommended tire pressure when you ride a mountain bike?

Information that you might need to help me.

Weight: 180lbs
Tire size: 27.5" X 2.10 (tube)
Full suspension Haro
Terrain for ride: Hard Pack Dirt (trail) with a bit of road (to get to the trail)

I have been riding all these while with about 51psi on both my front and rear. But I was alarmed when I aw on the internet, people riding with pressures as low as 18 rear and 16 front.

Withe the information I have given I hope someone could help me.

Any advises?
