1 millibar is equal to

Options

A. `100 Nm^(-2)`
B. `10 Nm^(-2)`
C. `1Nm^(-2)`
D. `1/100 Nm^(-2)`

Explanation

To find out how much 1 millibar is equal to in terms of Newton per meter square (Pascal), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Units**:
- We know that the unit of pressure we are dealing with is millibar.
- The SI unit of pressure is Pascal (Pa), which is defined as Newton per meter square (N/m²).

2. **Know the Conversion from Bar to Pascal**:
- We need to establish the relationship between bar and Pascal.
- It is known that 1 bar = 1 × 10^5 Pascal.

3. **Convert Millibar to Bar**:
- Since 1 millibar is a subunit of bar, we have:
- 1 millibar = 1/1000 bar (or 0.001 bar).

4. **Calculate Millibar in Terms of Pascal**:
- Now, we can substitute the value of 1 millibar in terms of bar into the equation we have for bar in terms of Pascal:
- 1 millibar = 0.001 bar = 0.001 × (1 × 10^5 Pascal).

5. **Perform the Calculation**:
- When we multiply:
- 0.001 × 10^5 = 10^2 (since 0.001 = 10^-3 and 10^5 = 10^5).
- Therefore, 1 millibar = 100 Pascal.

### Final Answer:
1 millibar is equal to 100 Newton per meter square (N/m²) or 100 Pascal (Pa).
