Convert Ounces-force to Kilograms-force

1 ounce-force is 0.02835 kgf. One ounce-force is exactly 0.028349523125 kilograms-force.

One ounce-force is 0.028349523 kilograms-force. To convert ounces-force to kilograms-force, multiply by 0.028349523; to go the other way, divide by 0.028349523 or multiply by 35.273962. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A sixteenth of a pound-force.

What is an ounce-force?

A sixteenth of a pound-force. Spring tensions, switch actuation and small-motor specifications are given here.

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.

How many kilograms-force are in an ounce-force?

One ounce-force is 0.028349523 kilograms-force. Going the other way, one kilogram-force is 35.273962 ounces-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.
