When the prefix milli is used in the metric or SI system, a fundamental unit of measurement is multiplied by what factor?

Options

A. `10^3`
B. `10^(-3)`
C. `10^(-6)`
D. `10^(-2)`

Answer

To determine the factor by which a fundamental unit of measurement is multiplied when the prefix "milli" is used in the metric or SI system, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Prefix "Milli":**
- The prefix "milli" is a metric prefix that denotes a specific factor in the metric system.

2. **Identify the Factor for "Milli":**
- The prefix "milli" corresponds to a factor of \(10^{-3}\). This means that when you see "milli" in front of a unit, you are multiplying that unit by \(0.001\) or dividing it by \(1000\).

3. **Conclusion:**
- Therefore, when the prefix "milli" is used, a fundamental unit of measurement is multiplied by \(10^{-3}\).

### Final Answer:
When the prefix "milli" is used in the metric or SI system, a fundamental unit of measurement is multiplied by \(10^{-3}\).
