To convert from kilograms (kg) to hectograms (hg), we can use the following conversion factor:
1 \text{ kg} = 10 \text{ hg}
Given that we have 234 kg, we can set up a proportion to solve for the value in hectograms:
\frac{234 \text{ kg}}{1} = \frac{x \text{ hg}}{10}
Cross multiplying, we get:
234 \text{ kg} \times 10 = x \text{ hg}
x = 2340 \text{ hg}
Therefore, 234 kg is equal to 2340 hg.
\boxed{2340 \text{ hg}}
