13.4: Pressure Units and Conversions - Chemistry LibreTexts
WEBA pascal is a very small amount of pressure, so the most useful unit for everyday gas pressures is the kilopascal \(\left( \text{kPa} \right)\). A kilopascal is equal to 1000 pascals. Another commonly used unit of pressure is the atmosphere \(\left( \text{atm} \right)\).

9.1: Gas Pressure - Chemistry LibreTexts
WEBOct 27, 2022 · The SI unit of pressure is the pascal (Pa), with 1 Pa = 1 N/m 2, where N is the newton, a unit of force defined as 1 kg m/s 2. One pascal is a small pressure; in many cases, it is more convenient to use units of kilopascal (1 …
Pascal (Pa) | Definition & Conversions | Britannica
WEBA 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 1,000 newtons per square metre is more commonly used.
Pascal (unit) - Wikipedia
WEBThe 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. The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1]
