How to use Winters' pressure conversion table

1) Find the COLUMN with the unit of measure you want to convert from and move down that COLUMN until you find the number "1"

2) Move horizontally within the same ROW to find the Conversion Factor of the scale you want

3) Multiply the Conversion Factor (number in the box) by the amount you are changing from to get the pressure in the scale you are seeking (e.g. 50 bar to be converted to psi scale: 1 bar equals to 14.5038 psi (Conversion Factor), so 50 bar equals to 725.19 psi)
