Ounce-Force Converters

Convert ounces-force (ozf) to newtons, pounds-force, grams-force, kilograms-force, dynes and other force units.

What this tool does

Convert ounces-force (ozf) to newtons, pounds-force, grams-force, kilograms-force, dynes and other force units. Type an amount in ounces-force, choose the units, and the tool converts it to newtons. It offers 10 force units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 10 options, including Micronewton, Millinewton, Newton, Dyne, Gram-force, Kilogram-force (kilopond). Starts as Ounce-force.
  • To: Choose one of the same 10 units as "From". Starts as Newton.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.

Worked examples

Conversions from ounces-force to newtons:

  • 1 ozf ≈ 0.278014 N
  • 5 ozf ≈ 1.390069 N
  • 10 ozf ≈ 2.780139 N
  • 50 ozf ≈ 13.900693 N
  • 100 ozf ≈ 27.801385 N

Multiply the number of ounces-force by about 0.278014 to get newtons. The factor follows from exact definitions. It has more digits than fit here, so it is shown rounded.

Limitations

  • Converts a force from one unit to another. It does not work out force from mass and acceleration.
  • Kilogram-force, gram-force, pound-force and ounce-force are gravitational units, defined with standard gravity of 9.80665 m/s2. They measure a force, not a mass.

FAQs

Q: How many newtons is one ounce-force?
A: One ounce-force is about 0.2780 newton. It is exactly one sixteenth of a pound-force (4.4482216152605 N).
Q: How many ounces-force are in a pound-force?
A: There are exactly 16 ounces-force in one pound-force.
Q: Is an ounce-force the same as a fluid ounce or a weight ounce?
A: An ounce-force is the force of one avoirdupois ounce of mass under standard gravity. It is not a fluid ounce, which measures volume.
