Answer

To answer the question, "Mass is a constant quantity for a given body and is measured in," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mass**:
- Mass is defined as the amount of matter in a body. It is an inherent property of matter and does not change regardless of the object's location or the gravitational force acting on it.

2. **Characteristics of Mass**:
- Mass is a constant quantity for a given body, meaning it remains the same under normal conditions.
- Mass is conserved, which means it cannot be created or destroyed in a closed system.

3. **Fundamental Quantity**:
- Mass is considered one of the fundamental quantities in physics. It is one of the seven base quantities in the International System of Units (SI).

4. **SI Unit of Mass**:
- The SI unit of mass is the kilogram. It is abbreviated as "kg." This unit is used universally to measure mass.

5. **Conclusion**:
- Therefore, the answer to the question is that mass is measured in kilograms (kg).

### Final Answer:
Mass is a constant quantity for a given body and is measured in kilograms (kg).
