Hi Marcoscavd,
Yep! You can change the weight and dimension units at WooCommerce > Settings > Products.
This field defines the units of measure for the size and weight of the product .
but in my case my product is sold per kg , while the same can be vedido 200.34 grams , but when I enter the weight woocommerce works only with unity and not by weight.
Preço do Kg = $33 | Preço da grass = $0,33
Produto Weight = 421grass
Produto Weight X price = $13,89
Are you looking to calculate the price based on the weight the user inputs? If so, something like this should help: https://www.woothemes.com/products/measurement-price-calculator/
