Table of pressure units and conversion factors
Unit Conversion
To convert FROM pressure VALUE 1 in pressure UNITS 1
TO pressure VALUE 2 in pressure UNITS 2, calculate as follows:
VALUE 2 = VALUE 1 x FACTOR 1
Note:
The conversion factor for pressure units referenced [1] are calculated for a water
temperature of 4°C. Pressure units referenced [2] are calculated for a water tem-
perature of 68°F these units are normally used in the USA.
