Pascal disimbolkan dengan Pa satuan turunan SI untuk tekanan atau tegangan. Satu pascal setara dengan satu newton per meter persegi. Dalam kehidupan sehari-hari, pascal dikenal karena penggunaannya untuk menyatakan laporan tekanan udara yang umumnya dilaporkan dalam hektopascal (1 hPa = 100 Pa). Satuan ini dinamakan menurut nama Blaise Pascal, seorang matematikawan, fisikawan dan juga filsuf asal Prancis.
Keterangan: N adalah newton, m: meter, kg: kilogram, dan s: detik/sekon.
