Metric Ton-force (tf)
Definition: The weight of a 1,000-kilogram (one metric ton) mass under standard Earth gravity; equal to exactly 9,806.65 newtons.
History: A scaled-up extension of the kilogram-force within the same pre-SI gravitational metric system, created to express very large forces — crane capacities, ship displacements, press forces — without unwieldy strings of zeros.
Current use: Common today in heavy engineering and industrial contexts such as hydraulic press ratings, crane lifting capacities, and shipping/cargo weight specifications in countries that use the metric system.
Dyne (dyn)
Definition: The CGS (centimeter-gram-second) unit of force, defined as the force needed to accelerate a 1-gram mass at 1 centimeter per second squared; equal to exactly 10⁻⁵ newtons.
History: Introduced in the late 19th century as part of the CGS system of units used by physicists before the SI system (built on meters, kilograms, and seconds) became the international standard in the mid-20th century.
Current use: Largely historical today, but still appears in older physics literature and in some specialized fields like surface tension measurement, which is traditionally expressed in dynes per centimeter.

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 Metric Ton-force → Dyne: multiply by 9.80665E+08. For example, 1 tf × 9.80665E+08 = 9.80665E+08 dyn.
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 tf equals 9.80665E+08 dyn. For scale, that's about 9806.65× the weight of an average apple (roughly 1 N, or 0.00010197162 tf) — and a 150 lb (about 667 N) adult's body weight would be roughly 0.068015071 tf.
Frequently Asked Questions
How many Dynes are in 1 Metric Ton-force?
1 Metric Ton-force (tf) equals exactly 9.80665E+08 Dynes (dyn).
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.
