Pressure Conversion

Use the below pressure conversion chart to convert into different units of pressure. Choose your beginning unit value on the left and then find the cell where it aligns with the final value you seek across the top of the chart . Multiply the value in that cell by your starting unit of pressure to calculate your desired unit of pressure. Example: Converting from “inch Hg” to “BAR” would require multiplying your starting pressure value by 0.0339. 15”Hg x 0.0339 = 0.5079 BAR
