Like the title. How are we able to convert pounds, which are a unit of force, to kg which is a unit of mass, using a simple scale factor. How are electronic scales able to give us a unit of mass when they measure by using the force enacted on the scale by gravity because all they are doing is using a conversion factor between pounds and kg that shouldn’t exist

Since the pull of gravity is pretty much constant on Earth’s surface, a measure of mass implies a weight and vice versa.
You are right, mass is measured in kilograms and slugs, and weight in Newtons and pounds. However, people don’t bother with the difference because we something with 454g of mass has 1 pound of weight (while on Earth).
