Method and calculation
Convert pressure through the pascal: value × source factor / target factor. Factors relative to pascal: Pa = 1; kPa = 1000; MPa = 1000000; bar = 100000; mbar = 100; atm = 101325; psi = 6894.757293168; mmHg = 133.322387415.
Inputs and settings
Pressure Converter accepts Value (minimum 0); From unit (Pa, kPa, MPa, bar, mbar, atm, psi, mmHg); To unit (Pa, kPa, MPa, bar, mbar, atm, psi, mmHg).
Worked example
Pressure Converter example — Value: 1; From unit: "Pa"; To unit: "kPa". Computed output: { "value": 0.001, "unit": "kPa", "baseValue": 1, "baseUnit": "pascal" }
Output and limitations
Pressure describes normal force distributed over area. A standard atmosphere is exactly 101325 pascals, whereas bar is exactly 100000 pascals. Gauge and absolute readings need a reference-pressure adjustment before conversion; choosing another unit alone cannot supply that offset.
