Force Converter: Convert Newtons, lbf, kgf and More
The Force Converter changes values among SI, CGS, gravitational, and imperial absolute force units, including newtons, kilonewtons, dynes, kilogram-force, pound-force, poundals, and ounce-force. It uses 1 dyne = 1e-5 N, 1 kgf = 9.80665 N, and 1 lbf = 4.4482216152605 N; standard gravity is g₀ = 9.80665 m/s². Choose the source and target units to read the converted value.
The Force Converter is a browser-based force unit converter for changing measurements among newtons, kilonewtons, dynes, kilogram-force, pound-force, poundals, and ounce-force. Use it to convert force units online when a calculation, specification, or report uses a different unit from the one you need. It brings several common force unit systems together so you can select a source unit and a target unit and read the converted value.
The units span different measurement systems. The newton is the SI unit of force, while the dyne belongs to the CGS system and equals 1e-5 N. Kilogram-force and pound-force are gravitational units defined using standard gravity, g₀ = 9.80665 m/s²: one kilogram-force is exactly 9.80665 N, and one pound-force is exactly 4.4482216152605 N. The poundal is an imperial absolute unit, defined as 1 lb·ft/s². Select the units that match your input and desired result.
SI, CGS, gravitational, and imperial absolute units express force using different conventions. Converting between them makes measurements easier to compare and share when project documents or audiences use different systems. For example, you can check a value in newtons against one stated in pound-force, or convert a group of measurements instead of handling each conversion by hand.
The Force Converter runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. It is free to use, and after the page has loaded, conversion works offline without a server connection. The tool is useful for developers, engineers, students, and DevOps professionals who need to work with force measurements across unit systems.
Step 1: Enter the force value you want to convert. Use the measurement from your calculation, specification, or reference.
Step 2: Choose the source unit for the value and the target unit you need. Available units include newtons, kilonewtons, dynes, kilogram-force, pound-force, poundals, and ounce-force.
Step 3: Read the converted figure in the target unit. The conversion uses the relationships between the selected force units.
Step 4: For a set of measurements, convert the values you need and check each result in the unit used by your audience or project.
Use case: Convert force measurements when a source document uses SI units but your project uses gravitational or imperial units.
Use case: Check a force value in the unit your audience, team, or technical documentation expects.
Use case: Convert a set of values instead of rounding each measurement by hand.
Use case: Compare a value recorded in newtons with one specified in kilogram-force or pound-force.
Use case: Prepare force measurements for engineering notes, reports, or reference material that uses a different unit system.
Use case: Review a calculation that uses dynes or poundals by converting its force value to another supported unit.
