1 E+18 m²

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.

1 E+18 m²

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

1 E+19 m²

1 E+20 m²

1 E+21 m²

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

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

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.
