"The pounds is a unit of force, but the kilogram isn't.

LoL! Ok if you say so....

But I tell you, if I drop a kilo of iron on your toe, you're going to feel it, and wish it were only a pound.

(you are a very confused person)

Since I’m so confused, please straighten me up by telling me what is the SI unit of mass. Thank you in advance.

a kilo is a unit of weight

Would you accept the magazine Physics World as knowing what a kilogram is? See this article for the following statement:

Scientists have proposed two ways to redefine the unit of mass. The first is based on the Planck constant and requires a 1-kilogram mass to be supported against Earth’s gravity using a precisely measured magnetic force.

See, a kilogram is a unit of mass, and when it has a gravitational acceleration applied to it, you get a force. That whole F=ma thing.

A kilogram is a unit of mass. It exerts a force (weight), because of gravitational attraction between masses (the earth and the kg of mass), but the force will change based upon the gravitational attraction between the two.
