How can I create a custom liquid that calculates the price per 100 Gramm?

[huks]

Hello,

I need a flexible price that is always based on the variant and weight selected. Hence I need to display below my normal price a custom liquid that calculates the price divided by the weight times 100 (for the 100g).

I tried it like the following code in a custom liquid field on the product page:
{% assign price_per_100g = variant.price | divided_by: variant.weight | times: 100 %} {% assign price_per_100g = price_per_100g | money %} <p>Price per 100g: {{ price_per_100g }}</p>

Somehow it won't display anything besides the Price per 100g. I am using the Dawn theme, but this shouldn't be theme specific I guess.

Hi @huks 
Can you please check the code below, It will work:

{% for variant in product.variants %}
      {% if variant.weight > 0 %}
        {% assign weight_in_grams = variant.weight %}
        {% assign price_per_100g = variant.price | times: 100 | divided_by: weight_in_grams %}
        <p>Price per 100g: {{ price_per_100g | money }}</p>
      {% else %}
        <p>Price per 100g: Not Available</p>
        {% endif %}
      {% endfor %}

Thanks for your help & sorry for the late response. Unfortunately it's not 100% the solution. It now writes down all prices at once, I need only the price for the variant selected.
