Grams, kilograms and pounds all measure mass. They’re just “stretched” differently by this or that factor.
There is also a “pound” - lbf - that’s a confusingly named separate unit for force. E.g. pressure can be measured in pounds per square inch - it is a force distributed over an area, not a mass.

and, most cursed of all, the gravitational acceleration on earth is one pound per pound (g = 1 lbf/lb)
Nothing makes you understand the need for metric like doing physics in us customary
