The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI). It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength.

In measurements of sound pressure or loudness of sound, one pascal is equal to 94 decibels SPL. The quietest sound a human can hear, known as the threshold of hearing, is 0 dB SPL, or 20 µPa.

A pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared. This unit is inconveniently small for many purposes, and the kilopascal (kPa) of …

The pascal (symbol: Pa) is the SI derived unit of pressure, internal pressure, stress, Young's modulus and tensile strength, named after the French mathematician, physicist, inventor, writer, and …

Pascal is a procedural programming language, designed in 1968 and published in 1970 by Niklaus Wirth and named in honour of the French mathematician and philosopher Blaise Pascal. Pascal runs on a …

Pascal is defined as the pressure exerted by a force of one newton (N) uniformly distributed over an area of one square metre (m²). In other words, 1 Pa = 1 N/m². It is a relatively small unit, which is …

Nov 26, 2025 · The pascal is defined by its constituent SI base units, establishing a precise scientific measure for pressure. One pascal is mathematically equivalent to a force of one newton exerted …

Blaise Pascal[a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer. Pascal was a child prodigy who was educated by his father Étienne …

One pascal equals one newton per square meter, which is a relatively small amount of pressure. Therefore, kilopascals (kPa) or megapascals (MPa) are often used in practical applications to …
