WooCommerce: Product weight order

Hello,
Is it possible to let customers set a weight of product that they want to order?
For example there is a meal, and customer wants to order 132 g of the product. I know there are variations and attributes, but as I know I can only set many variations and client can only choose between them. I want to let client write (set) a amount of weight that He or She wants to order.
Maybe there is any plugin or it’s a basic option?

Thank you!
