Pressure conversion

7 units, with Pa as the base. Every value in the factor table is the number you multiply by, so reading across a row converts out of that unit and reading down a column converts into it.

Factor table

Pressure conversion factors. Each cell is the value to multiply the row unit by to get the column unit.

The table gives the factor; the unit converter does the arithmetic, remembers the units you picked, and turns any conversion into a link you can share.
