Calculate for the si base unit for pressure

The SI base unit for pressure is the **pascal (Pa)**, which is defined as one **newton per square meter (N/m²)**. 

To break it down in terms of base SI units:

- **Pressure (Pa)** = Force / Area
- Force is measured in **newtons (N)**, and a newton is defined as **kg·m/s²** (kilogram·meter per second squared).
- Area is measured in **square meters (m²)**.

Thus, the pascal can be expressed as:

\[
1 \, \text{Pa} = 1 \, \frac{\text{N}}{\text{m}^2} = 1 \, \frac{\text{kg} \cdot \text{m/s}^2}{\text{m}^2} = 1 \, \frac{\text{kg}}{\text{m} \cdot \text{s}^2}
\]

Therefore, the SI base units for pressure are **kg·m⁻¹·s⁻²**.
