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.



Kilogram (kg)


The kilogram is the SI base unit of mass, representing the amount of matter in an object.



  • It is symbolized as kg.



  • Since 2019, the kilogram is defined by fixing the value of the Planck constant to exactly 6.62607015×10−346.62607015 \times 10^{-34} joule seconds, linking mass to fundamental physical constants.



  • Before this, it was defined by a physical platinum-iridium prototype.



  • It is the only SI base unit still using the prefix "kilo" in its name.



Key points:



  • 1 kg is the base unit of mass in the metric system



  • Defined using the Planck constant for high precision



  • Widely used globally in science, industry, and everyday life



The kilogram ensures accurate and universal mass measurements across the world.
