Solve x²kg to Grams: Converting Squared Variable Weight Units

To convert $x^2$ kilograms to grams, follow these steps:

• Step 1: Start from the given expression in kilograms, which is $x^2 \text{ kg}$.
• Step 2: Use the conversion factor: $1 \text{ kg} = 1000 \text{ gr}$.
• Step 3: Multiply the given $x^2$ by 1000 to convert it into grams.

Performing the multiplication, we have:
$x^2 \times 1000 = 1000x^2$

Therefore, the weight in grams is $1000x^2$.

The correct choice corresponding to this result is:

• Choice 1: $1000x^2$

In summary, the equivalent of $x^2$ kilograms in grams is $1000x^2$.
