Format product weight to export as grams

Hello,

Is there a PHP code I could add in your plugin misc settings to modify weight field, which has a woocommerce value of kilograms(kg) to be exported as grams(g)? I.E. Product weight in woocommerce is 2.1kg(value:2.1), I want it to be exported as 2100g(value:2100). I think what I need is that woocommerce weight field value would be multiplied by 1000 when exporting.

I know that I can change product weight to be kg or g in woocommerce settings, but this method would not work because one of my shipping partners require me to import product weight in their system as grams(g), another one as kilograms(kg).

Thank you for your help.
