Product Weight | Order Endpoint

I called the order Endpoint, I have required to get product weight with ML that available in different fields.
Moslty 30ML, 40ML,50ML etc mentionded in the following fields
1- product_title
2- full_title
3- sellable_title
See Screenshot:

Is there any way to get the Actual weight, without splitting the TITLES (and retrieve the ML value)

Please help
