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
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.
