Pascal (Pa)

Quantity: Pressure · Category: Derived SI

The pascal is the SI unit of pressure: one newton of force spread over one square meter. It is named after Blaise Pascal, who studied how pressure transmits through fluids.

Relation to SI

1 Pa = 1 N/m² = 1 kg/(m·s²)

Examples

• Atmospheric pressure at sea level is about 101,325 pascals.
• A sharp knife edge can exceed a million pascals under your hand.
