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}10−15 (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.
The mass of the Earth is approximately 5.972 × 10²⁴ kilograms.
This massive value represents the total amount of matter contained in our planet, influencing gravity, orbital dynamics, and geological processes.
Summary:
Mass ≈ 5.972 × 10²⁴ kg
Determines Earth’s gravitational pull
Fundamental for planetary science and astronomy
