Force is a fundamental concept in physics that describes the interaction between objects. The newton (N) is the base unit of force in the International System of Units (SI), defined as the force required to accelerate a mass of 1 kilogram at 1 meter per second squared.
In engineering and everyday applications, different force units are used depending on the context. Pound-force (lbf) is commonly used in the United States and represents the force exerted by gravity on a mass of 1 pound. Kilogram-force (kgf) is the force exerted by gravity on a mass of 1 kilogram under standard gravitational acceleration (9.80665 m/s²).
Our converter handles the full spectrum of force units from micronewtons (µN) used in micro-mechanics to kilonewtons (kN) used in structural engineering. Whether you're calculating the force of a falling object, analyzing structural loads, or designing mechanical systems, this tool provides accurate conversions for all your force-related calculations.
