How to set converting tv field in snippet?

Question

MODX

There is a snippet that takes the price for sorting, the price is in euros and it needs to be converted to another currency, how can this be done with the price field in this snippet ?

$key_placeholder = 'show_block';

$modx->unsetPlaceholders($key_placeholder);

$params = array(
  'parents' => $id,
  'includeTVs' => 'price,power,overclocking,fuel_consumption,body_type,fuel_type,number_of_doors,rwd,transmission',
  'select' => 'id,pagetitle',
  'limit' => '20',
  'depth' => '2',
  'returnIds' => '1'
);

$where = array();

if(isset($_GET['price-from']) && isset($_GET['price-to'])) {
  $where[] = 'price >= ' . $_GET['price-from'];
  $where[] = 'price <= ' . $_GET['price-to'];
}

$where[] = 'template = 12';
$childrens = array();

$params['where'] = '["' . implode(' AND ', $where) . '"]';

$output = $modx->runSnippet('pdoResources', $params);
if (!empty($output)) {
  $childrens = explode(',', $output);
  
  foreach($childrens as $child_id) {
  $all_childrens = $modx->getParentIds($child_id, 2, array());
  $id_series = array_pop($all_childrens);
  if ($id_series == $id) {
    return $modx->setPlaceholders(array(
    $key_placeholder => 1,
    'child_id' => $child_id
    ));		
  }
  }
  
  return $modx->setPlaceholders(array(
  $key_placeholder => 0
  ));
}
