Newton Converter

Convert newtons to pounds-force, kilograms-force, dynes and other force units.

What this tool does

Convert newtons to pounds-force, kilograms-force, dynes and other force units. Type an amount in newtons, choose the units, and the tool converts it to pounds-force. 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 Millinewton, Newton, Kilonewton, Meganewton, Dyne, Gram-force. Starts as Newton.
  • To: Choose one of the same 10 units as "From". Starts as Pound-force.

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 newtons to pounds-force:

  • 1 N ≈ 0.224809 lbf
  • 5 N ≈ 1.124045 lbf
  • 10 N ≈ 2.248089 lbf
  • 50 N ≈ 11.240447 lbf
  • 100 N ≈ 22.480894 lbf

Multiply the number of newtons by about 0.224809 to get pounds-force. 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.
  • There is no separate equivalent-mass figure. Converting to kilogram-force gives the mass in kilograms that would weigh that much under standard gravity.
  • 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 pounds-force is one newton?
A: One newton is about 0.2248 pound-force. One pound-force is exactly 4.4482216152605 newtons.
Q: How many newtons is one kilogram-force?
A: One kilogram-force is exactly 9.80665 newtons, based on standard gravity.
Q: What is a newton?
A: A newton is the force that gives a mass of one kilogram an acceleration of one meter per second squared.
