Ok..I was bored so I made a chart in case any new-b's wanted to know. Basically take your bar or HKPA number and just multiply by 14.5 - but this is more like a quick ref guide I guess:

HKPA -------------- PSI
1.00 ======== 14.50
1.05 ======== 15.22
1.15 ======== 15.90
1.20 ======== 17.40
1.25 ======== 18.12
1.30 ======== 18.85
1.35 ======== 19.57
1.40 ======== 20.30
1.45 ======== 21.02
1.50 ======== 21.75
1.55 ======== 22.47
1.60 ======== 23.20
1.65 ======== 23.92
1.70 ======== 24.65
1.75 ======== 25.37
1.80 ======== 26.10
1.85 ======== 26.82
1.90 ======== 27.55
1.95 ======== 28.27
2.00 ======== 29.00
