One formula used to convert psi to bar is:
1 psi
= (32.174 lbm /1 lbf s2)x(0.45359237 kg /1 lbm)x(144 in2/1 ft2)x(1 ft /0.3048 m)
x(1 m s2 /105 kg)
= 0.06894747 bar
So 1 bar = 14.503795 psi
The Math behind it.
As psi is an imperial unit and bar is metric unit, we some constants
1 lb = 0.45359237 kg
1 ft = 0.3048 m
1 ft2 = 12 in x 12 in = 144 in2
And we have to rearrange some units
1 bar = 105 Pa = 105 Nm-2
And N = kg ms-2
so 105 Pa = 105 kgm-1s-2
Also note when applying newton's second law using imperial units we need to use a gravity constant 32.174 lbm /1 lbf s2
Metric
m x a = F
1 kg x 9.81 ms-2 = 9.81 N
Imperial units
m x a = F
1 lbm x 32.174 fts-2 ≠ 32.174 lbf need to use gravity constant gc
m x (a/gc) = F
1 lbm x (32.174 fts-2 / (32.174 lbm /1 lbf s2) = 1 lbf
Bars x 14.5 = psi
1 bar = 100 kilopascal (kPa)

1 bar is 14.5038 psi. Scroll down to related links and look at "Conversion of pressure or stress units".
Use this formula: psi x 0.07031 = kg/cm2
Use this formula: psi x 0.07031 = kg/cm270 psi x 0.07031 = about 4.921 kg/cm2
