Why the sum looks like this

The pound is the smaller unit, so the same weight takes fewer kilograms. One pound is 0.45359237 kg, so 160 pounds is 160 × 0.45359237 = 72.5747792 kg. There is no offset to worry about, unlike temperature, so doubling the pounds always doubles the kilograms.

Check it in your head
