The question from the image states:

"The average mass of a grain of sand from a certain beach is \( 6 \times 10^{-7} \) kilograms.  
What is this value in grams? Give your answer in standard form."

### Solution:

1. **Convert kilograms to grams:**
   \[
   1 \text{ kilogram} = 1000 \text{ grams}
   \]
   
   So, to convert the mass from kilograms to grams, we multiply by 1000:

   \[
   6 \times 10^{-7} \text{ kilograms} \times 1000 = 6 \times 10^{-7} \times 10^3 \text{ grams}
   \]

2. **Simplify the powers of 10:**

   \[
   6 \times 10^{-7 + 3} = 6 \times 10^{-4} \text{ grams}
   \]

Thus, the mass of the grain of sand in grams is \( 6 \times 10^{-4} \) grams.

This is the answer in standard form.
