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 10−1510^{-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.



Planck Mass


The Planck mass is a fundamental physical constant in theoretical physics, representing a natural unit of mass based on fundamental constants: the speed of light, gravitational constant, and Planck’s constant.


Its value is approximately 2.18 × 10⁻⁸ kilograms (about 22 micrograms).


The Planck mass is significant in quantum gravity and string theory, marking a scale where quantum effects of gravity become strong and classical physics breaks down.


Summary:



  • Approximately 2.18 × 10⁻⁸ kg (22 micrograms)



  • Derived from fundamental physical constants



  • Important in quantum gravity and theoretical physics
