pascal in Electrical EngineeringPowered by COBUILD (pæskæl) or Pa
Word forms: (regular plural) pascals
(Electrical engineering: General) A pascal is a unit of pressure, where one pascal is equal to the force of one newton exerted on one square meter. ⇒ Because the human ear perceives pressure changes logarithmically over a large range, the sound pressure level is measured in pascals and converted to decibels. ⇒ The standard way to rate microphone sensitivity is to apply a 1 kHz sound source equal to one pascal and then measure the output level and express it in mV/PA. ⇒ A pascal is a unit of pressure, where one pascal is equal to the force of one newton exerted on one square meter.
Word originsThis word is named for Blaise Pascal (1623-62), the French mathematician and physicist.
