pounds.

\newline

\text{kg}

Understand conversion factor: Understand the conversion factor between pounds and kilograms. $\newline$ We know that $1$ kilogram equals $2.2$ pounds. To find the weight in kilograms, we need to divide the weight in pounds by the conversion factor. $\newline$ Calculation: $77$ pounds $\div$ $2.2$ pounds per kilogram = $35$ kilograms.
