# Pascal conversions

The pascal conversion selector on this page selects the pressure/stress measurement unit to convert to starting from pascals (Pa). To make a conversion starting from a unit of pressure other than pascal, simply click on the "Reset" button.

## About pascal

The **pascal** is the SI derived unit of pressure. One pascal is equal to 1,000 millipascals (mPa), or 0.01 hectopascals (hPa), or 0.001 kilopascals (kPa), or 10^{-6} megapascals (MPa) or 10^{-9} gigapascals (GPa), which are units of pressure in the SI.

The pascal (Pa) is also equal to 9.86923267 × 10^{-6} atmospheres (atm), or 10^{-5} bars (bar), or 0.007500616 millimeters of mercury at 0 °C (mmHg), or 0.00401463 inches of water at 4 °C (inH_{2}O), or 0.000145037 pounds per square inch (psi), or 0.020885434 pounds per square foot (psf) or 0.00750061683 torr (Torr).

The pascal is equal to one newton per square meter (1 Pa = 1 N/m^{2}). The newton (N) is a unit of force in the SI while the square meter (m^{2}) is a unit of area in the SI.

The pascal unit is named after the famous French physicist, mathematician and philosopher Blaise Pascal who lived between 1623 and 1662.
