Step 1: Defining the pound and kilogram terms

Pound (lb) -

It is a unit of mass in the British imperial unit. It is a\({\raise0.7ex\hbox{$1$} \!\mathord{\left/

{\vphantom {1 {2.20462}}}\right.\kern-\nulldelimiterspace}

\!\lower0.7ex\hbox{${2.20462}$}}\)of a kilogram. There is also a term called themetric pound,which is half of the kg. It is denoted bylb.

\(1\,\,lb\,\, = \,\,{\rm{0}}{\rm{.453592}}\,\,kg\)

Kilogram (kg) -

It is a unit of mass in the International System of Units (SI base unit). It is approximately twice of pound’s mass. It is thethousandthtimes of gram. It is denoted bykg.

\(1\,\,kg\,\, = \,\,{\rm{2}}{\rm{.20462}}\,\,lb\)

It is given that the mass of the weight lifter is 197 lb while the lifting mass is 192 kg.

We know,

\(1\,\,kg\,\, = \,\,{\rm{2}}{\rm{.20462}}\,\,lb\)

For conversion from kg to lb,

Therefore, the mass lifted in pounds is 423 lb.
