Answer 1

public function convertWeightToKg($weight, $weightUnit, $roundPrecision = 3)

{

switch ($weightUnit) {

case 'LBS':
    $finalWeight=$weight*453.592;
    return $finalWeight;
    break;

case 'KILOGRAM':
    $finalWeight=$weight*1000;
    return $finalWeight;
    break;

default:
    return $weight;

} }
