Kilogram-force Converters

Convert kilograms-force (kgf, also called kiloponds) to newtons, pounds-force, dynes and other force units.

What this tool does

Convert kilograms-force (kgf, also called kiloponds) to newtons, pounds-force, dynes and other force units. Type an amount in kilograms-force (kiloponds), choose the units, and the tool converts it to newtons. It offers 15 force units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one from 15 options, including Gram-force, Kilogram-force (kilopond), Tonne-force (metric), Micronewton, Millinewton, Newton. Starts as Kilogram-force (kilopond).
  • To: Choose one of the same 15 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 kilograms-force (kiloponds) to newtons:

  • 1 kgf = 9.80665 N
  • 5 kgf = 49.03325 N
  • 10 kgf = 98.0665 N
  • 50 kgf = 490.3325 N
  • 100 kgf = 980.665 N

Multiply the number of kilograms-force (kiloponds) by 9.80665 to get newtons. Both units are exact definitions, so 9.80665 is the exact factor: 1 kgf = 9.80665 N.

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 kilogram-force?
A: One kilogram-force is exactly 9.80665 newtons, because it is defined as one kilogram times standard gravity of 9.80665 m/s2.
Q: Is a kilopond the same as a kilogram-force?
A: Yes. Kilopond (kp) is another name for the kilogram-force, and the two are shown together as one unit.
Q: What is a sthene?
A: The sthene is the force unit of the old metre-tonne-second system. One sthene is exactly 1000 newtons, equal to one kilonewton.
