Conversion Formula
daN = pN × 1.000000000e-13
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 Decanewtons
One decanewton (daN) is exactly 10 N. It is industrially significant in Europe because 1 daN ≈ 1 kgf (9.80665 N, a 2% difference), allowing gauges calibrated in daN to give readings that approximate kilogram-weight while remaining SI-compliant. ISO 376 and EN 13791 load-cell calibration standards use daN. ECE Regulation 16 (vehicle seat belts) and EN ISO 13857 (machinery safety distances) specify forces in daN. Continental European spring gauges and tensile testers routinely carry daN scales. 1 daN = 10 N = 1.01972 kgf = 2.24809 lbf.
