Force Converter
Convert applied force units across SI, US customary, gravitational metric, CGS, and FPS absolute systems. The converter uses newtons as the base route and separates force from everyday mass labels.

Convert load, thrust, and weight-force labels
Load and thrust values
Convert newtons, pounds-force, kilogram-force, and kips when engineering notes mix force systems.
Full comparison table
Review every supported engineering unit after one input so adjacent checks do not require repeated typing.
SI base route
Trace each answer through a standard SI base unit instead of relying on an isolated result.
Force conversion formula
The converter normalizes every source value to newtons before scaling into the target force unit.
Working formulas
Base conversion
newtons = value x newtons per source unit
Every force value is first converted into newtons.
Target value
target value = newtons / newtons per target unit
The newton value is divided by the target unit factor.
Pound-force relationship
1 lbf = 4.4482216152605 N
This factor anchors lbf, ozf, and kip conversions.
Symbols
- N - newton
- SI derived unit of force.
- kgf - kilogram-force
- Force due to standard gravity on one kilogram of mass.
Force, mass, standard gravity, and usable precision
This live converter translates a force value through newtons and generates all supported rows from the same input. It is not a load chart and does not infer force from a mass unless the applicable acceleration is already represented by a force unit such as kilogram-force.
Newton base and gravitational units
One newton is the force that gives one kilogram an acceleration of one metre per second squared. Kilonewtons and meganewtons are exact SI-prefix scales. Pound-force and kilogram-force are force units built from defined mass/length relationships and conventional standard gravity.
A kilogram by itself is mass, not force. This registry uses 9.80665 N for 1 kgf and 4.4482216152605 N for 1 lbf. A real object's weight can differ with local gravitational acceleration, so do not relabel an unqualified mass value as force.
Worked conversion: 100 pound-force
100 lbf x 4.4482216152605 N/lbf = 444.822161526 N
The same force is approximately 0.444822 kN. The converter retains useful factor precision, while an engineering report should round to match the original load measurement or specification.
Separate conversion from design decisions
Copy the force label with the result: lbf is not the same symbol as lb mass, and kgf is not kg. The formatter removes floating-point artifacts and limits the screen value to 12 significant digits.
Loads, thrust, pulls, and reactions can share force units while having very different physical meaning. Unit conversion alone does not establish a load path, allowable stress, factor of safety, or equipment capacity.
Use this page to translate a known force. If the known quantity is pressure, convert its units first and retain the loaded area before deriving force.
Open the pressure converter for force-per-area valuesLimits to keep with the result
- The page does not convert mass to force without an acceleration model.
- No structural, lifting, mechanical, or safety capacity is calculated or approved.
- Local gravity, dynamic loading, and measurement uncertainty remain outside the factor conversion.
Why force labels need care
Separates mass from force
- A kilogram is mass, while a kilogram-force is force under standard gravity.
- Pounds-force, kips, and ounces-force are force labels, not mass labels.
- The table keeps gravitational and absolute force systems visible.
Useful for engineering specs
- Loads, pulls, thrust ratings, and structural examples can be normalized to newtons.
- Kips and kilonewtons are both available for structural comparisons.
- Small CGS and FPS values remain available for legacy references.
Useful for force and load conversion
Structural checks
Convert loads between kN, N, lbf, and kip.

Physics practice
Compare SI force with gravitational and CGS force units.
How it works in three quick steps.
Enter force
Type a load, thrust, pull, weight-force, or classroom force value.
Choose units
Select newtons, kilonewtons, pounds-force, kilogram-force, kips, dynes, or related labels.
Compare rows
Use the table to see how SI, gravitational, and US customary force labels relate.
Save force conversions
Copy engineering result
Copy the converted value with source and target labels for calculations, specs, worksheets, or review notes.
Print the table
Print the comparison table when shop, lab, classroom, or field work needs multiple adjacent units visible.
Keep the SI route visible
Use the formula notes to confirm whether the conversion passed through N m, N, kg/m3, or m3/s.

About this force converter
Force conversion often gets tangled with mass wording. In everyday language, weight may mean body mass, but in science and engineering weight is a force. The converter keeps labels such as newton, pound-force, kilogram-force, and kip explicit so the physical quantity remains clear.
This page normalizes force values through newtons and shows each supported unit in one comparison table. That makes it useful for structural loads, mechanical pulls, thrust ratings, spring problems, and older CGS or FPS references.
