The decibar conversion selector on this page selects the pressure/stress measurement unit to convert to starting from decibars (dbar). To make a conversion starting from a unit of pressure other than decibar, simply click on the "Reset" button.
The decibar is a unit of pressure equal to 10,000 pascals (1 dbar = 10,000 Pa), the SI derived unit of pressure.
One decibar (dbar) is also equal to 100 hectopascals (hPa), or 10 kilopascals (kPa), or about 0.0986923267 atmospheres (atm), or 0.1 bars (bar), or 75.006168 millimeters of mercury at 0 °C (mmHg), or 40.1463 inches of water at 4 °C (inH2O), or 1.450379 pounds per square inch (psi), or 208.854343 pounds per square foot (psf) or 75.006168 torr (Torr).
The decibar is equal to 100,000 dynes per square centimeter (1 dbar = 100,000 dyn/cm2). The dyne (dyn) is a unit of force in the centimetre-gram-second (CGS) system of units while the square centimeter (cm2) is a unit of area in the SI.
The decibar is commonly used as a unit of pressure in oceanography.
