Convert Ounces-force to Kilonewtons

1 ounce-force is 0.000278 kN. One ounce-force is exactly 0.000278013850954 kilonewtons.

One ounce-force is 2.7801 × 10^-4 kilonewtons. To convert ounces-force to kilonewtons, multiply by 2.7801 × 10^-4; to go the other way, divide by 2.7801 × 10^-4 or multiply by 3596.9431. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A sixteenth of a pound-force.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert ounces-force to kilonewtons?

  1. 1.Take the measurement in ounces-force.
  2. 2.Multiply by 2.7801 × 10^-4 — that is how many kilonewtons fit in one ounce-force.
  3. 3.To go back the other way, divide by 2.7801 × 10^-4, or multiply by 3596.9431.

Worked example: 25 ounces-force to kilonewtons

Formula
ozf × 2.7801 × 10^-4 = kN
Arithmetic
25 × 2.7801 × 10^-4 = 0.00695 kN
Answer
25 ozf = 0.00695 kN

The factor is rounded for display; the figure above is computed from the full value.

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 kilonewton?

A thousand newtons. Structural loads, anchor ratings and climbing gear are marked here: a 22 kN carabiner holds about 2.2 tonnes.

How many kilonewtons are in an ounce-force?

One ounce-force is 2.7801 × 10^-4 kilonewtons. Going the other way, one kilonewton is 3596.9431 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.
