How to Convert Earth's Mass to Petagram
To convert Earth masses to kg: multiply by 5.9722 × 10²⁴.
M⊕ = 5.9722 × 10²⁴ kg ≈ 5.972 Yg (yottagrams). Earth = 1 M⊕ by definition.
For example, 1 Earth's Mass (M⊕) = 5.972200e+12 Petagram (Pg).

About Earth's Mass (M⊕)
Definition
The Earth mass is the mass of planet Earth, approximately 5.972 × 10²⁴ kilograms.
Mathematical Relationship
M⊕ = 5.9722 × 10²⁴ kg ≈ 5.972 Yg (yottagrams). Earth = 1 M⊕ by definition.
Conversion Formula
To convert Earth masses to kg: multiply by 5.9722 × 10²⁴.
Practical Applications
Expressing exoplanet masses (e.g., 'a planet of 3 Earth masses'), moon masses, and asteroid masses.
Interesting Facts
Earth gains about 40,000 tonnes of mass per year from cosmic dust — but that's only 10⁻¹⁷ of its total mass.
Common Mistakes
Earth's mass is hard to visualize. The key insight: it's known from G × M⊕ (the gravitational parameter), not M⊕ alone.
Educational Tips
Cavendish 'weighed the Earth' by measuring G. If you know g (9.8 m/s²) and Earth's radius, you can calculate M⊕ = gR²/G.
About Petagram (Pg)
Definition
The petagram equals 10¹⁵ grams or one billion tonnes (one gigatonne).
Mathematical Relationship
1 Pg = 10¹⁵ g = 10¹² kg = 10⁹ tonnes = 1 gigatonne.
Conversion Formula
To convert Pg to tonnes: multiply by 10⁹. To convert Pg to Tg: multiply by 1,000.
Practical Applications
Global carbon budgets: about 10 Pg of carbon are emitted annually from fossil fuels.
Interesting Facts
The total mass of all life on Earth is estimated at about 550 Pg of carbon.
Common Mistakes
Confusing Pg (petagram = 10¹⁵ g) with PB (petabyte). In mass contexts, P = peta = 10¹⁵.
Educational Tips
1 Pg C = 1 gigatonne of carbon. Annual human CO₂ emissions are about 10 Pg C — a key climate figure.
