Factory Oil Pressure Gauge 71 Charger??s

[ipstrategies]

Can someone here tell me what the marks on the Factory Oil Pressure Gauge would equal in pounds?
It is a 71 Charger 383 Magnum with Ralleye Gauges and as you know only marks as the picture shows.
Also what mark would be considered normal at  operating temp?
Thanks

top mark should be 80 PSI , the first mark will be 25-30 psi & with a stock pump it should idle in that range at 3000 rpm it should be in the middle
