About hectopascal

The hectopascal is a unit of pressure equal to 100 pascals (1 hPa = 100 Pa), the SI derived unit of pressure.

The hectopascal (hPa) is also equal to 0.1 kilopascals (kPa), or 0.0001 megapascals (MPa), or 0.000986923267 atmospheres (atm), or 0.001 bars (bar), or 0.7500616 millimeters of mercury at 0 °C (mmHg), or 0.401463 inches of water at 4 °C (inH2O), or 0.0145037 pounds per square inch (psi), or 2.0885434 pounds per square foot (psf) or 0.750061683 torr (Torr).

The hectopascal is equal to 100 newtons per square meter (1 hPa = 100 N/m2). The newton (N) is a unit of force in the SI while the square meter (m2) is a unit of area in the SI.

The hectopascal is used as a unit of pressure in meteorology.
