Femtogram [fg]


The femtogram is a metric unit of mass equal to one-quadrillionth of a gram.



  • 1 femtogram = 0.000000000000001 grams = 10⁻¹⁵ grams



  • 1 femtogram = 10⁻¹⁸ kilograms



  • Symbol: fg



Key Facts:



  • Used in highly sensitive scientific research, including molecular biology, physics, and nanotechnology



  • The prefix "femto-" means 101510^{-15} (one quadrillionth)



  • Measures incredibly small masses such as molecules, atoms, and nanoparticles



The femtogram allows for the detection and measurement of ultrafine masses at the atomic and molecular scale.



Kilogram-force second squared per meter (kgf·s²/m)


This is a derived unit combining mechanical units and force.



  • Kilogram-force (kgf): A unit of force defined as the force exerted by gravity on one kilogram of mass at standard gravity (9.80665 m/s²).



    • 1 kgf ≈ 9.80665 newtons (N).




  • The unit kgf·s²/m can be interpreted as a measure related to mechanical impedance or compliance in some physics or engineering contexts, combining force, time squared, and distance.



Breakdown:



  • Force (kgf) × Time² (s²) / Length (m)



  • It has dimensions of mass × time² / length (since 1 kgf ≈ 9.81 N = kg·m/s²)



This unit is uncommon but might appear in specific engineering or physics formulas related to dynamic systems or mechanical vibrations.
