Unit of ________ is the same in all the systems of measurements.

Answer

To solve the question "Unit of ________ is the same in all the systems of measurements," we need to identify a physical quantity that has a consistent unit across different measurement systems.

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for a physical quantity whose unit remains unchanged across various systems of measurement.

2. **Identify Common Physical Quantities**: Consider common physical quantities such as length, mass, time, temperature, etc.

3. **Analyze Each Quantity**:
- **Length**: The unit of length varies (meters in the SI system, feet in the FPS system).
- **Mass**: The unit of mass also varies (kilograms in the SI system, pounds in the FPS system).
- **Time**: The unit of time is consistently measured in seconds across all systems.

4. **Conclusion**: Since time is measured in seconds in all systems (SI, FPS, CGS, etc.), we conclude that the answer to the question is time.

### Final Answer:
The unit of **time** is the same in all the systems of measurements.
