To help compare orders of magnitude of different surface areas, we list here examples of areas of the order of 1025 square metres, i.e. those between 10 quintillion km² and 100 quintillion km². See also areas of other orders of magnitude.
- Areas smaller than 10 quintillion km²
- 1.0·1025 m² is equal to:
- 1 E+25 m²
- an area of ten quintillion km²
- 2.6·1025 m² - area swept by Uranus's orbit around Sun
- 6.4·1025 m² - area swept by Neptune's orbit around Sun
- Areas larger than 100 quintillion km²
