Convert force instantly — type a value, pick your units, and every other common unit updates live below. 100% free, runs entirely in your browser, no sign-up.
Every unit below updates live from the value you enter in the "From" field above.
A newton is defined as the force needed to accelerate one kilogram at one meter per second squared — small enough that everyday forces (like the weight of an apple, roughly 1 N) are convenient to express in it. Pound-force and kilogram-force are older "gravitational" units, defined by how much a standard mass weighs under standard gravity, which is why their factors involve the constant 9.80665.
Yes. It's completely free with no sign-up, and every conversion runs locally in your browser via JavaScript — the numbers you type are never sent to our servers.
Each unit uses its standard, internationally defined conversion factor, calculated in full precision and only rounded for display. Results are accurate to at least 6 significant figures.
This page intentionally covers the most commonly used force units rather than an exhaustive engineering list. Use the suggestion button in the bottom-right corner of any page to request a unit and we'll consider adding it.
