Force Converter (kN to kg)
Newtons, kgf and lbf — exact — and the mass whose weight a force is.
Type a force in plain words — “10 kN to kg”, “75 kg to N”, “500 lbf in kN”, “2 t to kN” — or use the boxes below.
Rounded · kgf = kN ÷ 0.00980665
- Kilonewton: 1 kN = 1,000 N
- Kilogram-force (kilopond): the weight of 1 kg under standard gravity = 9.80665 N exactly; also called the kilopond (kp)
Mass and weight
Weight is the force of gravity on a mass: W = m × g. Under standard gravity (9.80665 m/s²) a 1 kg mass weighs 1 kgf = 9.80665 N.
Leave empty for standard gravity, or type your local value.

About the Force Converter (kN to kg)
Convert force between newtons (mN, N, kN, MN), the gravitational units gram-force, kilogram-force (kilopond) and tonne-force, the pound-force family — ounce-force, pound-force, kip and the US and UK ton-forces — and the dyne and poundal. Type in either box and the other updates; the table underneath shows the value in every unit, with exact factors: 1 kgf is exactly 9.80665 N and 1 lbf exactly 4.4482216152605 N.
The common question “how many kg is a kN?” mixes mass and force. Under every result the page shows the mass whose weight that force is — 1 kN is the weight of about 101.97 kg — and Mass and weight turns a mass into its weight in N, kN, kgf and lbf. Both use standard gravity, 9.80665 m/s², unless you type the gravity where you are. Quick convert understands 10 kN to kg and 75 kg to N too.
How to use it
- Type a number in From and pick its unit, then pick the unit you want in To — or type
10 kN to kgin Quick convert and press Enter. - Read the result, its formula and the mass it is the weight of; the table shows the same force in every unit.
- Under Mass and weight, type a mass to get its weight. Leave Gravity empty for standard gravity, or type a local value in m/s².
- Copy the result or a link, download the table as CSV, or convert a list of loads under Convert a list of values.

Common uses
- Crane, hoist, jack and press capacities given in tonnes or kgf, compared with kN.
- Load cells, force gauges and spring balances in N, kgf, gf, lbf and ozf.
- Structural and geotechnical loads in kN, MN, kip and ton-force.
- Physics homework: weight from mass, dynes, poundals and newtons.
Mass, weight and “kN to kg”
A kilogram is a unit of mass; a newton is a unit of force. The 3rd General Conference on Weights and Measures settled the confusion between them: weight is a force — the mass times the acceleration of gravity — and the standard weight of a body is its mass times standard gravity, 9.80665 m/s².
So a 1 kg mass weighs 9.80665 N (one kilogram-force), and a force of 1 kN is the weight of 1,000 ÷ 9.80665 ≈ 101.97 kg. The page shows that mass under every result. Real gravity differs slightly from place to place and with height, so a mass weighs a little more or less than its standard weight; if you know your local g, type it under Mass and weight.
Gravitational units: kgf, tonne-force and pound-force
- Kilogram-force (kgf, also called the kilopond, kp) = 9.80665 N exactly; the gram-force is a thousandth of it and the tonne-force (tf) a thousand times it, 9.80665 kN. Gauges and load ratings that say “kg” or “tonnes” for a force mean these.
- Pound-force (lbf) = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N exactly; an ounce-force is 1/16 of it, a kip 1,000 of it, the US short ton-force 2,000 and the UK long ton-force 2,240.
- The poundal (the force that accelerates 1 lb by 1 ft/s²) is 0.138254954376 N, and the CGS dyne 10⁻⁵ N.
Where the factors come from
- NIST SP 811, Appendix B: kilogram-force (kilopond) = 9.80665 N and dyne = 10⁻⁵ N exactly; pound-force ≈ 4.448222 N, kip ≈ 4,448.222 N, ton-force (2,000 lbf) ≈ 8,896.443 N, ounce-force ≈ 0.2780139 N and poundal ≈ 0.1382550 N.
- With standard gravity the pound-force is exactly 4.4482216152605 N (NIST SP 811 footnotes), which gives every pound-based factor exactly.
- Standard gravity, 980.665 cm/s², is the conventional value of the 3rd CGPM.
Limitations
- Masses for a force use standard gravity unless you type a local value; the page does not estimate gravity for a place.
- A unit converter only: it does not check whether a load is safe for a lifting device, a fixing or a structure.
- Weights on the Moon or other planets: use Weight on Other Planets.
- Results are exact fractions shown to 10 significant digits (marked ≈ when rounded).

Frequently asked questions
How many kg is 1 kN?
A force of 1 kN is the weight of about 101.97 kg under standard gravity: 1,000 N ÷ 9.80665 m/s². In kilogram-force, 1 kN ≈ 101.97 kgf.
How many newtons is 1 kg?
A 1 kg mass weighs 9.80665 N under standard gravity — exactly one kilogram-force. Strictly, kilograms measure mass and newtons force, so this is the weight of the mass.
What is the difference between kg and kgf?
kg is mass, the amount of matter; kgf is force, the weight of 1 kg under standard gravity, 9.80665 N. On Earth the two numbers are almost the same, which is why scales and gauges can be marked in “kg”.
How do I convert lbf to newtons?
Multiply by 4.4482216152605 (exactly): 100 lbf = 444.82216152605 N, about 0.445 kN.
How many kN is a tonne?
A tonne of mass weighs one tonne-force, 9.80665 kN, under standard gravity. A crane rated “10 t” lifts a load whose weight is about 98 kN.
Does my weight in newtons change from place to place?
Slightly, because gravity varies a little over the Earth’s surface and with height; your mass does not change. Type your local gravity under Mass and weight to use it instead of standard gravity.
