Frequently Asked Questions

Which weight conversions are supported?

Milligrams, grams, kilograms, ounces, and pounds appear together in one grid. Enter any unit and read the others.

Should I use net or packaged weight?

Use the weight definition required by the field you are filling—often packaged unit weight for fulfillment planning. Do not enter bare product net weight when the workflow expects the sellable unit ready for FBA.

What is the difference between unit and shipping weight?

Unit weight describes the sellable item input you provide. Shipping weight is what Amazon's fee lookup may use after tier rules, dimensional weight comparison, and rounding—they are related but not always identical.
