One field value to other field in Sales Invoice Item

I want to add two columns in Sales Invoice Item 1. Actual Weight 2. Charged Weight
If I enter 30 as actual weight then minimum charged weight should be 50 or 100 as defined in Sales Order as minimum weight and if it is greater than minimum then charged weight should be Actual weight.

Please suggest
