Conversion Tables - Pressure Units

Input for Quality Decisions

 
To convert pressure from one unit to another:
  1. Start at column heading with units to convert from.
  2. Move down the same column to number "1".
  3. Move across this row to the column with units heading you are converting to.
  4. Multiply the number in this table cell times the amount you are converting from to get
    the new value in converted units.
