Pascala (sinboloa: Pa) Nazioarteko Unitate Sistemako presio-unitatea da. Definizioz ${\text{ 1 N}}$-eko indar batek berarekiko normala den ${\text{1 m}}^{2}$-ko azalera duen gainazalean eragiten duen presioa da. Unitatearen izena Blaise Pascal (1623-1662) matematikari eta fisikari frantziarraren ohorez aukeratu zen.

$${\text{Pa}}={\frac {\text{N}}{{\text{m}}^{2}}}={\frac {\text{J}}{{\text{m}}^{3}}}={\frac {\text{kg}}{{\text{m}}\cdot {{\text{s}}^{2}}}},$$

non ${\text{N}}$ (newton), ${\text{m}}$ (metro), ${\text{J}}$ (joule), ${\text{kg}}$ (kilogramo), ${\text{s}}$ segundo unitateak diren.

Honako baliokidetzak ditu bestelako presio-unitateekin:

$${\text{1 Pa}}=10^{-5}{\text{ bar}}={\text{10 baria}}=9,86923\times 10^{-6}{\text{atm}}.$$
