1 E+18 m²

From Wikipedia, the free encyclopedia

To help compare sizes of different surface areas, we list here areas between 10¹⁸ square metres and 10²⁴ square metres, i.e. those between 1 trillion km² and 1 quintillion km².

[edit] Smaller areas

• Areas smaller than 1,000,000 million km²

[edit] 1 E+18 m²

• 1 trillion km² is equal to:
  • 1 E+18 m²
  • 1 square gigameter
• 6,100,000 million km² -- surface area of the Sun

[edit] 1 E+19 m²

[edit] 1 E+20 m²

[edit] 1 E+21 m²

• 1 quadrillion km² is equal to 1 E+21 m²
• 1.6 quadrillion km² — Ringworld (total area; fictional)

[edit] 1 E+22 m²

• 1.1 · 10²² m² - area swept by Mercury's orbit around Sun
• 3.7 · 10²² m² - area swept by Venus' orbit around Sun
• 7.1 · 10²² m² - area swept by Earth's orbit around Sun

[edit] 1 E+23 m²

• 1.6 · 10²³ m² — area swept by Mars' orbit around Sun
• 2.81 · 10²³ m² — surface area of a Dyson Shell with a radius of 1 AU.

[edit] Larger areas

• Areas larger than 1 E+24 m² (1,000,000,000,000 million km²)
