Pressure conversion matrix

Every pair of pressure units in one table. Rows are the from unit, columns the to unit. Click any cell to open the full converter.

How to read: each cell shows how many column-unit equal 1 row-unit. For example, in length: 1 km → 1000 m. The diagonal cells (—) are the same unit and not conversions.

How to use this table

Find your starting unit in the left column (From). Move across that row to the target unit (To) at the top. The cell where they meet is the conversion factor — the number of target units equal to one starting unit.

Click any cell to open the full converter for that pair. Click any unit abbreviation (row or column header) to open that unit's encyclopedia page.
