SI Unit for Pressure Measurement
Pressure is defined as force applied perpendicular to the surface of an object per unit area over which that force is distributed. Mathematically, it's represented as:
$ P = \frac{F}{A} $
Where '$P$' is pressure, '$F$' is the force, and '$A$' is the area.
Identifying the SI Unit of Pressure
The International System of Units (SI) provides a standard set of units for scientific and everyday measurements. For pressure, the derived SI unit is the Pascal, symbolized as 'Pa'.
- Pascal (Pa): This is the standard SI unit for pressure. 1 Pascal is equal to 1 Newton per square meter (1 N/m²).
- Radian (rad): This is the SI unit for measuring plane angles.
- Steradian (sr): This is the SI unit for measuring solid angles.
- Ampere (A): This is the SI base unit for measuring electric current.
Therefore, the correct SI unit for pressure is the Pascal.
