About converting Ounce-force to Newtons
Ounce-force (ozf) and Newtons (N) are both units of force, so converting between them is a single multiplication: multiply your Ounce-force figure by 0.278. Ten Ounce-force comes to 2.7801 Newtons, and a hundred works out at 27.8014 Newtons.
Rule of thumb: going from Ounce-force to Newtons divides, so the figure always shrinks — it takes about 3.5969 Ounce-force to make a single Newton. If your answer came out bigger, you have the conversion the wrong way round.
What is an Ounce-force?
The ounce-force is the pound-force scaled down: the force standard gravity exerts on one ounce of mass. It exists because a great deal of engineering deals in small forces, and "a fraction of a pound" is an unhelpful way to say them. American component data sheets are where it lives — the operating force of a microswitch or push-button, spring tensions, and the torque of small motors, which is routinely specified in ounce-inches. Everywhere else the same measurements are made in newtons, so most people outside US component engineering never meet it.
What is a Newton?
The newton is the SI unit of force, and it is defined with unusual clarity: the force that accelerates one kilogram at one metre per second squared. There is nothing arbitrary in it and no historical artefact — it falls straight out of the kilogram, the metre and the second. It is named after Isaac Newton, whose second law is the sentence the definition is built from. In practice it is a small unit; holding an apple in your palm takes roughly one newton, which is a pleasing coincidence given the story. That smallness is why structural work runs in kilonewtons.
To put both in perspective: pressing a keyboard key takes roughly 2 ounce-force, while holding a small apple takes about one newton.

Multiply the number of Ounce-force by 0.278. For example, 10 Ounce-force = 2.7801 Newtons.
What is 100 Ounce-force in Newtons?
100 Ounce-force is equal to 27.8014 Newtons.
How do I convert Newtons to Ounce-force?
Multiply the Newtons value by 3.5969 (or divide by 0.278).
Is this Ounce-force to Newtons conversion exact?
The definition is exact — Ounce-force and Newtons are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
