How do you convert newtons to pounds-force?

One newton equals 0.22481 pounds-force (lbf). To convert newtons to lbf, multiply by 0.22481. To convert lbf to newtons, multiply by 4.44822. For example, 1 kN (1000 N) equals 224.81 lbf.

What is a kilogram-force?

A kilogram-force (kgf) is the force exerted by a one-kilogram mass under standard gravity (9.80665 m/s squared). One kgf equals exactly 9.80665 newtons. It is a legacy unit still used in some engineering contexts, particularly for hydraulic pressure rated in kgf per square centimetre.

A kip is a unit of force equal to 1000 pounds-force (1 kilopound-force). It is used primarily in US structural engineering to express large forces and loads. One kip equals approximately 4448.22 newtons or 4.448 kN.

Force Converter

Force is a push or pull that acts on an object, measured in SI units as the newton (N), defined as the force that accelerates a one-kilogram mass at one metre per second squared. In practice, engineering work spans a huge range of magnitudes: the thread tension in a sewing machine might be measured in millinewtons, the load on a building column in kilonewtons, and the thrust of a large rocket in meganewtons. Meanwhile, much of the structural and mechanical engineering literature written before metrication, particularly from the United States and United Kingdom, uses imperial and customary units such as pounds-force (lbf), kips (kilopounds-force), and ounce-force. This converter handles the full range of common force units in one place. Select the unit you are converting from, enter your value, and all other units update instantly. The units covered are newton (N), kilonewton (kN), meganewton (MN), millinewton (mN), pound-force (lbf), kilogram-force (kgf), kip (1000 lbf), and dyne (the CGS unit, 10 to the minus 5 newtons). All conversions are exact within double-precision arithmetic and are based on the exact definition that one pound-force equals 4.44822162 newtons.

How it works

All conversions use newtons as the base unit. Conversion factors: 1 kN = 1000 N; 1 MN = 1,000,000 N; 1 mN = 0.001 N; 1 lbf = 4.44822 N; 1 kgf = 9.80665 N; 1 kip = 4448.22 N; 1 dyne = 0.00001 N. The input value is first converted to newtons, then divided by each factor to produce the remaining units.

Worked example

Convert 1 kN to other units. 1 kN = 1000 N. Divided by 4.44822 = 224.81 lbf. Divided by 9.80665 = 101.97 kgf. Divided by 4448.22 = 0.2248 kip. Divided by 0.00001 = 100,000,000 dyne = 1.00 times 10 to the 8 dyne.
