The following code allows to show the price per kilo using WooCommerce and ACF by creating a price_per_kilo custom product field via ACF:

global $product;



$price = $product->get_price();



$weight = $product->get_weight();



$id = $product->get_id();



$value = 1000 * $price / $weight;



update_field('price_per_kilo', $value, $id); // this code updates data for this field



the_field('price_per_kilo', $product->$id ); //show price per kilo

However it shows a lot of digits when the result is not round, do you know how I can limit to two decimal places ?

My Answer:
>get_price();__$weight = get_field('weight', $product->get_id());__$price_per_kilo = $price / $weight;__echo number_format($price_per_kilo, 2);_

This code calculates the price per kilo by dividing the product price by the weight specified in the custom field 'weight'. The number_format() function is used to limit the result to 2 decimal places.
