I literally have no idea what a kg or km is. I know a km and a kg are some type of unit of distance or something but I have no reference for what they are.

If you tell me you live 20km away, you might as well have said you don’t know how far away you live. Wtf is 20 km? Is that a lot? Now if you said 20 miles, I could understand that. If you don’t know what a mile is that’s OK, you can say you live 2584375 bananas away or 0.0000000001 light seconds away or 69872 ar15s per bud light football field away but FOR THE LOVE OF FUCK STOP USING THE METRIC SHIT SYSTEM.
