Convert Kilograms-force to Pounds-force
1 kilogram-force is 2.204623 lbf. One kilogram-force is exactly 2.20462262185 pounds-force.
One kilogram-force is 2.2046226 pounds-force. To convert kilograms-force to pounds-force, multiply by 2.2046226; to go the other way, divide by 2.2046226 or multiply by 0.45359237. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The weight of one kilogram under standard gravity, exactly 9.80665 newtons by the defined value of that gravity.

What is a kilogram-force?
The weight of one kilogram under standard gravity, exactly 9.80665 newtons by the defined value of that gravity. Older European engineering drawings are full of it.
What is a pound-force?
The weight of one pound under standard gravity, exactly 4.4482216152605 newtons. A pound of mass and a pound-force are different quantities that share a name, which is why this unit exists at all.
How many pounds-force are in a kilogram-force?
One kilogram-force is 2.2046226 pounds-force. Going the other way, one pound-force is 0.45359237 kilograms-force. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
