I only work in bar these days and to convert it to psi I just typed "2.2bar in psi " into google and it came back with 31.9083 hence I said 32

1bar was 14lb per sq.in last time I checked but if Google is correct than I stand corrected.

Indeed I thought 1 atmosphere was 14psi however apparently its not, its 14.6959psi I have also just learnt that 1 bar is not one atmosphere

To quote the interweb 

 

The bar is defined using the SI derived unit, pascal: 1 bar ≡ 100,000 Pa ≡ 100,000 N/m2.

Thus, 1 bar is equal to:

1,000,000 Ba (barye) (in cgs units);
and 1 bar is approximately equal to:

0.987 atm
14.5038 psi absolute
29.53 inHg
750.06 mmHg

 

I guess its all to do with rounding up or down
