This tool uses SI and NIST conversion factors to compare force units quickly for reference. For official values in design loads, test reports, and equipment calibration, always confirm the original unit and the governing standard.
What is a force unit converter?
A force unit converter lets you compare force values across different systems such as newton (N), kilonewton (kN), kilogram-force (kgf), pound-force (lbf), and dyne (dyn). In mechanical, structural, material, and laboratory documents, the same force may be expressed in different unit systems, so reading the number alone can easily lead to mistakes.
This tool first converts the input into the shared base unit of newtons and then recalculates every supported unit from there. That makes it easy to compare SI, cgs, gravitational, and imperial/customary force units on one screen, while the most common units are surfaced first in summary cards.
When to use this tool
Force units show up in more places than many people expect. Structural calculations may use kN or N, while material testers and load cells may show kgf or lbf, and older references or academic material may still use dyn or pdl. That is why it helps to normalize units quickly before you interpret the number.
- Structural and mechanical design – Compare part loads or clamping force data in N, kN, and lbf
- Reading test results – Convert tensile or compression tester values from kgf or lbf into SI units
- Checking overseas manuals – Read lbf, kip, and short ton-force values from US-based documents in a familiar unit system
- Learning and education – Understand how force unit systems relate to each other and differ in scale
- Report preparation – Normalize mixed unit data before writing tables, notes, or summaries
Key features
The layout is designed to support many units without feeling crowded. Common units are highlighted in cards first, while the full conversion list remains available in the table below. One input updates 17 units at once, and preset buttons let you jump to familiar reference values immediately.
- 17 units at once – Supports µN, mN, cN, N, daN, kN, MN, dyn, gf, kgf, tf, ozf, lbf, kip, pdl, short ton-force, and long ton-force
- Summary cards – Highlights the input value, newton, kilonewton, kilogram-force, and pound-force first
- Quick example buttons – Instantly apply reference values such as 10 N, 1 kN, 1 kgf, 1 lbf, and 1 kip
- Copy buttons – Copy the numeric value from any row directly
- Decimal control – Switch between 2, 4, and 6 decimal places
How to use
Enter a value, choose the input unit, and adjust the number of decimal places if needed. The result updates as soon as the value or unit changes, so you can read the headline units in the top cards first and then compare the rest in the full conversion table.
- Enter a value: Type the force value you want to convert.
- Select a unit: Choose the source unit from SI, cgs, gravitational, or imperial/customary systems.
- Set precision: Pick 2, 4, or 6 decimal places for display.
- Check the result: Read the top result card and summary cards first for the most common units.
- Use the table: Compare every supported unit and copy the numeric value you need.

This tool uses 1 N as the common base for all calculations. SI-prefixed units such as µN, mN, cN, daN, kN, and MN are exact decimal multiples of the newton, so the converter treats them as µN = 10-6 N, mN = 10-3 N, cN = 10-2 N, daN = 10 N, kN = 103 N, and MN = 106 N. In the cgs system, 1 dyn = 10-5 N.
Gravitational units are converted using standard gravity g = 9.80665 m/s². That means 1 kgf = 9.80665 N, 1 gf = 0.00980665 N, and 1 tf = 9806.65 N. Pound-force is calculated using the NIST definition of the force exerted on one avoirdupois pound mass under standard gravity, which gives 1 lbf = 4.4482216152605 N. From there, the converter extends to 1 ozf = 1/16 lbf, 1 kip = 1000 lbf, 1 short ton-force = 2000 lbf, and 1 long ton-force = 2240 lbf. Poundal (pdl) is converted as 1 lb·ft/s² = 0.138254954376 N.
- 10 N → lbf: 10 ÷ 4.4482216152605 ≈ 2.248089 lbf
- 1 kgf → N: 1 × 9.80665 = 9.80665 N
- 1 kip → kN: 4448.2216152605 ÷ 1000 = 4.448222 kN
- 100000 dyn → N: 100000 × 10-5 = 1 N
Frequently Asked Questions
What is the difference between N and kgf?
N is the SI unit of force, while kgf is a gravitational unit based on the force acting on a 1 kg mass under standard gravity. They can represent the same physical force, but the numerical values differ because the unit systems are different.
Are lbf and lb the same thing?
In casual usage, lb is sometimes used as if it were a force unit, but strictly speaking lb refers to mass and lbf refers to force. If you want to avoid ambiguity, use lbf when you mean force.
Where is dyn used?
dyn is the cgs unit of force. It still appears in older physics references, some educational material, and historical documents in specialized fields. One dyne equals 0.00001 N.
Why are short ton-force and long ton-force different?
Short ton-force is based on 2000 lbf in the US customary system, while long ton-force is based on 2240 lbf in the British system. They look similar by name, but the underlying number of pounds is different, so the result is different too.
Why include small-force units such as µN, mN, and cN?
Small-force units matter in sensors, material testing, precision instruments, and educational experiments. Including them makes it easier to compare both tiny and large force values within the same tool.
Can I use these results directly in a test report or design document?
They are useful for quick conversion and comparison, but for actual design loads, test reports, quality documents, or equipment settings, you should follow the official unit definition and rounding rules required by the relevant organization or manufacturer.
