maybe if got another solution for this.
I think its enough when i add a ~ infront of the gramm price and only show 2 commas like it is.

But then i run into the next problem =)
I only want to show the ~ before prices witch are in a defined main category. All products witch are not in this product-category(or subcategory) should have the standard price output.

For showing “per gramm” after the price for this main category i have tried to change the /loop/price.php like this:

<?php
/**
 * Loop Price
 *
 * @author 		WooThemes
 * @package 	WooCommerce/Templates
 * @version     1.6.4
 */

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

global $product;
?>
<?php if ( $price_html = $product->get_price_html() ) : ?>
<?php 
	//Check for parent category - if id =23  show other price
	
	//Get parent category
	global $post;
$prod_terms = get_the_terms( $post->ID, 'product_cat' );
foreach ($prod_terms as $prod_term) {

    // gets product cat id
    $product_cat_id = $prod_term->term_id;

    // gets an array of all parent category levels
    $product_parent_categories_all_hierachy = get_ancestors( $product_cat_id, 'product_cat' );  

    // This cuts the array and extracts the last set in the array
    $last_parent_cat = array_slice($product_parent_categories_all_hierachy, -1, 1, true);
    foreach($last_parent_cat as $last_parent_cat_value){
        // $last_parent_cat_value is the id of the most top level category, can be use whichever one like
        if($last_parent_cat_value == 23):
			$product_price_per_100g = $product->get_price_including_tax() * 100;
		?>
			<span class="product_price headerfont"><?php echo $price_html." /g"; ?></span>
			 
			
		<?php
			echo number_format(
				$product_price_per_100g, // zu konvertierende zahl
				2,     // Anzahl an Nachkommastellen
				",",   // Dezimaltrennzeichen
				"."    // 1000er-Trennzeichen
			);
			echo " ".get_woocommerce_currency();
			echo " /100g";
		else:
?>
			<?php $product_price_per_g = $product->get_price_including_tax(); ?>
			<span class="product_price headerfont"><?php echo $product_price_per_g; ?></span>
			
		<?php endif; ?>
		<?php
    } 

}//foreach ENDE
	

?>
<?php endif;?>

The price output on this defined category and sub-categories was working but all other products witch was not in this categories didn’t output any price after.

Do you maybe have an idea what is wrong with this script ?

thank you for your answer. The problem is that i only need the price with 3 commas in one place. When i change it there to 3 commas i have this price view in the whole shop.

thank you for nice support. that did it.
