Kilogram-force (kgf)

Definition: The weight of a 1-kilogram mass under standard Earth gravity (9.80665 m/s²); also called a kilopond (kp) in some European engineering contexts.

History: Part of the older "technical" or "gravitational" metric system used throughout continental Europe before SI was formally adopted in 1960, where forces were measured against a standard weight rather than through Newton's second law directly.

Current use: Still used informally today for bicycle and automotive torque wrench ratings, rocket thrust in some legacy specifications, and consumer product load ratings, even though SI newtons are now the formal engineering standard.

Ounce-force (ozf)

Definition: The weight of a 1-ounce mass under standard Earth gravity, equal to 1/16 of a pound-force.

History: Derived directly from the pound-force using the same 16-ounces-to-a-pound relationship as the customary mass units, for situations where a pound-force is too coarse a unit.

Current use: Used for small, precise force measurements such as spring and gauge calibration, fishing line and tackle ratings, and small mechanical component testing in the US.

How Force Conversion Works

The Formula

Every unit here is defined by a fixed multiplier relative to the newton. To convert a value from one unit to another:

result = value × (factor of "From" unit ÷ factor of "To" unit)

For Kilogram-force → Ounce-force: multiply by 35.273962. For example, 1 kgf × 35.273962 = 35.273962 ozf.

Force vs. Mass: A Common Point of Confusion

Force and mass are not the same thing, even though units like kilogram-force make them look related. A kilogram is a unit of mass — how much matter an object contains — while a kilogram-force is a unit of force: specifically, the weight (gravitational pull) exerted on a 1 kg mass at Earth's surface. Mass stays the same anywhere in the universe; weight changes with gravity, so a 1 kg mass weighs 1 kgf on Earth but would weigh far less on the Moon. Newtons, pound-force, and the other units on this page all measure force (or weight), never mass.

SI vs. US Customary and Engineering Units

The newton is the SI standard and the default unit in physics, mechanical engineering, and international science everywhere. US structural and civil engineers instead work primarily in pound-force and, for large loads, kips (1,000 lbf) — the customary units baked into American building codes. Kilogram-force and metric ton-force persist informally in parts of Europe and Asia for everyday load ratings even though they were formally superseded by the newton decades ago, and the dyne survives mainly in older CGS-based physics literature and a handful of specialized surface-tension measurements.

Example

1 kgf equals 35.273962 ozf. For scale, that's about 9.81× the weight of an average apple (roughly 1 N, or 0.10197162 kgf) — and a 150 lb (about 667 N) adult's body weight would be roughly 68.015071 kgf.

Frequently Asked Questions

How many Ounces-force are in 1 Kilogram-force?

1 Kilogram-force (kgf) equals exactly 35.273962 Ounces-force (ozf).

What's the difference between kilogram and kilogram-force?

A kilogram measures mass, an intrinsic property of an object that never changes. A kilogram-force measures the weight (force) that Earth's gravity exerts on a 1 kg mass — 9.80665 newtons. The two are related by gravity, not interchangeable, which is why kilogram-force is considered a legacy "gravitational" unit rather than a proper SI unit.

Why do engineers use kips?

Structural loads on buildings and bridges routinely run into the hundreds of thousands of pounds-force. Expressing a beam's load capacity as "150,000 lbf" is unwieldy, so American structural engineers use the kip (1,000 lbf) to keep numbers compact and readable — "150 kip" instead — the same reasoning that leads metric engineers to prefer kilonewtons over newtons for large loads.

How accurate are these conversions?

Every conversion factor used here is the exact, internationally recognized value (e.g. 1 lbf = exactly 4.4482216152605 N, derived from the internationally standardized pound and standard gravity) — results are limited only by floating-point display precision, not by rounded conversion constants.
