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.
