Strictly, kilograms measure mass and pounds are also a unit of mass in this context, so the conversion is a direct one. In casual use people call both weight, which is why a bathroom scale can label either unit.

Is this conversion exact?

The underlying factor is exact by definition, because the pound is fixed at 0.45359237 kg. The only approximation is the rounding applied to the number you see on screen.

Is my data sent anywhere?
