Convert Short Ton-Force to Dynes
Convert Short Ton-Force (tf (US)) to Dynes (dyn) instantly and accurately.
Conversion Formula
dyn = tf (US) × 889644323.1
About Short Ton-Force
One short ton-force is the gravitational force on a US short ton (2,000 lb) - exactly 2,000 lbf ≈ 8,896 N. It is used in heavy US industry for hydraulic press force ratings, forging press capacities, crane lift ratings, and bulldozer drawbar pull. US rigging and lifting equipment is rated in short tons. Caution: short ton-force (8,896 N) vs metric tonne-force (9,807 N) vs long ton-force (9,964 N) introduces up to 12% ambiguity when 'ton capacity' is unqualified - a critical safety distinction. 1 short tf = 2,000 lbf = 2 kip = 8,896.44 N.
About Dynes
The dyne (dyn) is the CGS unit of force - the force to accelerate 1 g at 1 cm/s² - exactly 10⁻⁵ N. Surface tension is universally expressed in dyn/cm (= mN/m): water 72.8 dyn/cm; mercury 487 dyn/cm; ethanol 22.1 dyn/cm. Astrophysics and plasma physics papers use dyn/cm² for pressure; solar photon radiation pressure at Earth's orbit is ~4.56 × 10⁻⁵ dyn/cm². The dyne pairs naturally with other CGS units (poise, erg, gauss), which is why it persists in stellar modelling and X-ray binary spectra literature. 1 dyn = 10⁻⁵ N = 10 µN.
