Poundal (pdl)
Definition: A force unit from the English Engineering System's alternative "absolute" branch, defined as the force that accelerates a 1-pound mass at 1 foot per second squared — the imperial analog of the newton rather than a gravitational unit.
History: Introduced in the 19th century by British engineers and physicists seeking an imperial unit of force that, like the newton, was derived purely from mass and acceleration rather than from Earth's gravity, avoiding the ambiguity of using "pound" for both mass and weight.
Current use: Rarely used today outside historical British engineering texts and some physics education contexts illustrating the mass-based vs. gravity-based unit distinction.
Gram-force (gf)
Definition: The weight of a 1-gram mass under standard Earth gravity (9.80665 m/s²) — a gravitational unit of force rather than a purely mechanical one.
History: Emerged naturally from early gravitational ("technical") systems of units, where force was defined by the weight of a standard mass on Earth's surface rather than derived abstractly from mass and acceleration.
Current use: Used today mainly in small-scale contexts like textile yarn tension, food science, and some spring-scale instruments calibrated in grams-force rather than newtons.

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 Poundal → Gram-force: multiply by 14.098082. For example, 1 pdl × 14.098082 = 14.098082 gf.
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 pdl equals 14.098082 gf. For scale, that's about 0.14× the weight of an average apple (roughly 1 N, or 7.2330138 pdl) — and a 150 lb (about 667 N) adult's body weight would be roughly 4824.4202 pdl.
Frequently Asked Questions
How many Grams-force are in 1 Poundal?
1 Poundal (pdl) equals exactly 14.098082 Grams-force (gf).
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.
