1 `mu` g (micro gram) =____

Options

A. `10^(-10)`
B. `10^(-8)`
C. `10^(-6)`
D. `10^(-4)`

Answer

To solve the question "1 µg (microgram) = ____", we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Prefix**: The term "micro" is a metric prefix that denotes a factor of \(10^{-6}\). This means that 1 microgram is equal to one millionth of a gram.

2. **Convert Micrograms to Grams**: Since we are asked to express 1 microgram in terms of grams, we can use the conversion factor:
\[ 1 \, \text{µg} = 1 \times 10^{-6} \, \text{g} \]

3. **Final Answer**: Therefore, we conclude that:
\[ 1 \, \text{µg} = 0.000001 \, \text{g} \quad \text{or} \quad 1 \, \text{µg} = 10^{-6} \, \text{g} \]

### Summary:
1 µg (microgram) = \(10^{-6}\) g (grams).
