Submultiple micro is equal to

Options

A. `1//1000000`
B. `1//100000`
C. `1//10000000`
D. `1//1000`

Explanation

To determine what the submultiple "micro" is equal to, we follow these steps:

### Step-by-Step Solution:

1. **Understanding the term "micro":**
- The term "micro" is a metric prefix used in the International System of Units (SI). It denotes a factor of one millionth (1/1,000,000).

2. **Expressing "micro" in scientific notation:**
- In scientific notation, one millionth can be expressed as \(10^{-6}\). Therefore, we can write:
\[ \text{Micro} = 10^{-6} \]

3. **Converting to a fraction:**
- The expression \(10^{-6}\) can also be written as:
\[ \frac{1}{10^6} \]
- This means that one micro unit is equal to one divided by one million.

4. **Counting zeros:**
- To understand \(10^6\), we can count the zeros:
- \(10^6 = 1,000,000\) (which has 6 zeros).
- Thus, \(1 \text{ micro} = \frac{1}{1,000,000}\).

5. **Conclusion:**
- Therefore, the submultiple "micro" is equal to \(10^{-6}\) or \(\frac{1}{1,000,000}\).

### Final Answer:
Micro is equal to \(10^{-6}\).
