The factors are masses. One pound is 0.45359237 kg, so 70 kg displays as 154.324 lb. One stone is 6.35029318 kg, which is 14 pounds.
Force units such as newtons and pounds-force are on the force converter. A kilogram-force is not a kilogram.
Pounds and stones
Sixteen ounces make a pound, and fourteen pounds make a stone. The ounce in this list is the avoirdupois ounce, 0.028349523125 kg.
Metric tons
One metric ton is 1000 kg. It is not a US short ton of 2000 pounds. That short ton is not in the list.
