Convert Dynes to Kilogram-Force
Convert Dynes (dyn) to Kilogram-Force (kgf) instantly and accurately.
Conversion Formula
kgf = dyn × 1.019716213e-6
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.
About Kilogram-Force
The kilogram-force (kgf), also called the kilopond (kp), is the gravitational force on 1 kg under standard gravity - exactly 9.80665 N. It was the primary force unit in continental European engineering before SI. ISO 1000 (1973) and EU Directive 80/181/EEC deprecated it in favour of the newton. Spring and bathroom scales reading in 'kg' technically measure kgf. Older DIN and JIS materials standards give tensile strength in kgf/mm² (× 9.80665 = MPa). Hydraulic cylinder ratings in legacy European machinery use kgf or tonne-force. 1 kgf = 9.80665 N = 2.20462 lbf.
