Definition of Pascal

Pascal: The SI Unit of Pressure

The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter (N/m²). Named after the French mathematician and physicist Blaise Pascal, it is used extensively in scientific, engineering, and meteorological applications. The pascal is a relatively small unit, so larger multiples like kilopascal (kPa) and megapascal (MPa) are commonly used in practice.

Conversions to Other Units of Measurement:

  1. Bar: 1 pascal equals 0.00001 bar (or 1 bar = 100,000 Pa). This conversion is frequently used in industrial applications. For example, standard atmospheric pressure (101,325 Pa) equals approximately 1.01325 bar.
  2. PSI (Pound per Square Inch): 1 pascal equals approximately 0.000145038 psi. This conversion is essential for interfacing with equipment using imperial measurements. For example, 100,000 Pa equals approximately 14.5 psi.
  3. Atmosphere (atm): 1 pascal equals approximately 9.8692×10⁻⁶ atm. Standard atmospheric pressure is defined as exactly 101,325 Pa or 1 atm.
  4. Torr: 1 pascal equals approximately 0.00750062 torr. This conversion is commonly used in vacuum technology. For example, 133.322 Pa equals 1 torr.
  5. Millibar (mbar): 1 pascal equals 0.01 millibar. This conversion is frequently used in meteorology. For example, standard atmospheric pressure equals 1013.25 mbar.

The pascal is fundamental to pressure measurement, providing a standardized unit for scientific calculations and engineering specifications.

About the Pascal

Facts & Uses

  • SI derived unit of pressure: 1 Pa = 1 N/m². Named after Blaise Pascal (1623-1662), the French mathematician and physicist.
  • Universal in scientific publications, weather data (hectopascals on barometric charts), and engineering specifications.
  • The pascal is a very small unit for everyday pressures — atmospheric pressure is ~101,325 Pa, so weather forecasts use hectopascals (hPa) or kilopascals (kPa).
  • Used in fluid mechanics, vacuum measurements, materials science (stress and strain), and tire pressure in metric markets.

Curiosities

  • The pascal was adopted as the SI unit of pressure at the 14th CGPM in 1971, replacing the older mechanical units like dyne/cm² (CGS) and lbf/in² (imperial).
  • 1 Pa is roughly the pressure exerted by a thin layer of paper resting on a tabletop — about 0.0000099 atmospheres.
  • The millibar (mbar), traditionally used in meteorology, equals exactly 1 hPa (100 Pa). Most modern weather services have switched to hPa for SI compatibility.
  • Approximate equivalents: 1 Pa ≈ 0.000145 psi; 1 atm = 101,325 Pa = 1013.25 hPa = 14.696 psi.

Frequently Asked Questions

How many pascals are in one decibar?

One decibar equals 10000 pascals. To convert, multiply the decibar value by 10000. For the reverse, divide the pascal value by 10000 (or multiply by 0.0001).

What is 10 decibars in pascals?

10 decibars = 100000 pascals. This is one of the most commonly searched conversions for this pair.

How precise is the decibar-to-pascal conversion?

The factor 10000 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
