kilograms?

Hello, I am not sure I understand your question. Could you please give me an example of the input and output that you are looking to obtain?

Hello @pbosakov,
I want do something like this:

Let me know please. Thank you very much!

Hello,

Yes, you can achieve something similar with my calculator plugin. Drop-downs are a premium feature, but with the free version hosted here on www.ads-software.com you can easily enter kilograms and obtain a price quote.

Just FYI, the site you sent me as an example uses a different proprietary WordPress plugin which you might also consider for your needs: https://codecanyon.net/item/cost-calculator-wordpress-plugin/12778927

Best regards,
Petko
