Convert Ounces-force to Newtons

1 ounce-force is 0.278014 N. One ounce-force is exactly 0.278013850954 newtons.

One ounce-force is 0.27801385 newtons. To convert ounces-force to newtons, multiply by 0.27801385; to go the other way, divide by 0.27801385 or multiply by 3.5969431. 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 newton?

The SI unit: the force that accelerates one kilogram by one metre per second every second. Holding a small apple against gravity takes about one newton.

How many newtons are in an ounce-force?

One ounce-force is 0.27801385 newtons. Going the other way, one newton is 3.5969431 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.
