Document Summary

Kilo (k) = thousand = 1,000 = 1 x 103. Mega (m) = million = 1,000,000 = 1 x 106. Giga (g) = billion = 1,000,000,000 = 1 x 109. Tera (t) = trillion = 1,000,000,000,000 = 1 x 1012. Centi (c) = hundredth = 0. 01 = 1 x 10-2. Milli (m) = thousandth = 0. 001 = 1 x 10-3. Micro ( ) = millionth = 0. 000001 = 1 x 10-6. Nano (n) = billionth = 0. 000000001 = 1 x 10-9. 1 micrometre (1 m) = 1 m / 1 million = 10 6 m. 1 millimetre (1 mm) = 1 m / 1 thousand = 10 3 m. 1 kilometre (1 km) = 1,000 m = 103 m. Atmospheric thickness: troposphere (bottom portion that has storms): 11 km, exosphere (top portion): 550 km. Ocean depth: average: 4 km, deepest (e. g. mariana trench): 11 km.
