Frequently Asked Questions
Is this tool really free?
▼
Yes, completely free with no limits and no sign-up. Everything runs in your browser with no server costs.
Is my data sent to a server?
▼
No. All conversion math happens directly in your browser. Nothing you type is ever sent anywhere.
What units are supported?
▼
11 units: Newton, Kilonewton, Meganewton, Millinewton, Dyne, Kilogram-force, Gram-force, Pound-force, Ounce-force, Poundal, and Kip.
What is the difference between Newton and Kilogram-force?
▼
A Newton is the standard scientific unit of force. A kilogram-force is the force exerted by gravity on one kilogram of mass, about 9.807 Newtons. Kilogram-force is informal but still widely used.
What is Pound-force?
▼
Pound-force (lbf) is the force exerted by gravity on one pound of mass, about 4.448 Newtons. It is the standard force unit in US engineering.
What is a Kip?
▼
A kip is 1,000 pound-force. It is used in structural engineering in the United States for large-scale load calculations.
What is a Dyne?
▼
A dyne is a very small unit of force equal to 0.00001 Newtons. It is used in physics, particularly in older scientific literature.
What is a Poundal?
▼
A poundal is the force needed to accelerate one pound of mass at one foot per second squared, about 0.138 Newtons. It is rarely used today.
How accurate are the conversions?
▼
The tool uses standard conversion factors and displays up to 10 significant figures. Results are accurate for everyday, educational, and professional use.
Can I see all conversions at once?
▼
Yes. Below the main result, the tool shows the same force in every other unit in a scrollable list.
What Is Force Converter?
Force Converter is a free tool that converts between 11 force units right in your browser. It covers the Newton family (millinewton to meganewton), gravitational units (kilogram-force, gram-force), US engineering units (pound-force, ounce-force, kip, poundal), and the classical dyne. Nothing you type is ever sent anywhere - all math runs locally on your device.
The result updates live as you type, and a full conversion table shows the same force in every other unit at once. Use the swap button to flip your units instantly, or copy the result to your clipboard in one click.

Tips for Best Results
Newton is the standard
The Newton (N) is the standard SI unit of force. 1 N is the force needed to accelerate 1 kilogram at 1 meter per second squared.
1 kgf is about 9.81 N
Kilogram-force is the weight of 1 kg under standard gravity. Many scales and specifications still use kgf, so this conversion comes up often.
1 lbf is about 4.45 N
Pound-force is the standard force unit in US engineering. Convert to Newtons when working with international standards.
Kip for structural loads
1 kip = 1,000 pound-force. Structural engineers in the US use kips to avoid writing large numbers of pounds.
Dyne is very small
1 dyne = 0.00001 N. It appears in older physics papers and CGS-system calculations.
