A very good 197-lb weight lifter lifted 192 kg in a move called the clean and jerk. What was the mass of theweight lifted in pounds?

Pound (lb) -

It is a unit of mass in the British imperial unit. It is a \({\raise0.7ex\hbox{$1$} \!\mathord{\left/ {\vphantom {1 {2.20462}}}\right.}\!\lower0.7ex\hbox{${2.20462}$}}\) of a kilogram. There is also a term called the metric pound, which is half of the kg. It is denoted by lb.

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

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,

\(192kg = 192\left( {kg \times \frac{{2.20462lb}}{{kg}}} \right) = 192 \times 2.20461 = 423lb\)

Therefore, the mass lifted in pounds is 423 lb.
