About Piconewtons
A piconewton (pN) is 10⁻¹² N - the force scale of molecular biology and nanotechnology. Optical and magnetic tweezers apply 0.1-100 pN forces to single DNA strands and protein complexes. Unzipping one DNA base pair requires ~10-15 pN; a kinesin motor protein stalls at ~7 pN. AFM cantilevers resolve piconewton van der Waals forces between single atoms and surfaces. The covalent C-C bond ruptures under ~4,000 pN in controlled AFM pulling experiments. These forces underpin mechanobiology, drug-target mechanics, and nanofabrication. 1 pN = 10⁻¹² N.
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.
