Pressure units
- Pascal (Pa) β The pascal (Pa) is a unit of pressure in the International System of Units (SI). It is the reference unit for all pressure conversions on this site.
- Hectopascal (hPa) β The hectopascal (hPa) is a unit of pressure in the International System of Units (SI). 1 hectopascal equals 100 pascals. This value is exact by definition.
- Kilopascal (kPa) β The kilopascal (kPa) is a unit of pressure in the International System of Units (SI). 1 kilopascal equals 1,000 pascals. This value is exact by definition.
- Bar (bar) β The bar (bar) is a metric unit of pressure accepted for use with the SI. 1 bar equals 100,000 pascals. This value is exact by definition.
- Psi (psi) β The psi (psi) is a unit of pressure used in both the imperial and US customary systems. 1 psi equals 6,894.757293 pascals.
- Standard Atmosphere (atm) β The standard atmosphere (atm) is a unit of pressure. 1 standard atmosphere equals 101,325 pascals. This value is exact by definition.
- Millimeter of Mercury (mmHg) β The millimeter of mercury (mmHg) is a unit of pressure. 1 millimeter of mercury equals 133.3223874 pascals.
