About Pond

The pond (p), also called gram-force (gf), is the gravitational force on 1 g under standard gravity - exactly 9.80665 × 10⁻³ N. It belongs to the metric gravitational technical system that dominated continental European engineering before SI. One thousand ponds = one kilopond (kp) = kilogram-force (kgf). Laboratory balances reading in grams technically measure pond, not mass. Older Mettler and Sartorius balance specs quote spring forces in pond. Pre-SI textile tensile strength was expressed in pond/tex. 1 p = 1 gf = 9.80665 mN = 0.001 kgf.

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.
