  1. Metric Prefixes Going Back & Forth

  2. Tera (Trillion): 1012 Giga (Billion): 109 Mega (Million): 106 kilo (thousand): 103 hecto (hundred): 102 Deka (ten): 101 deci (tenth): 10-1 centi (hundredth): 10-2 milli (thousandth): 10-3 micro (millionth): 10-6 nano (billionth): 10-9 Angstrom unit: 10-10 pico (trillionth): 10-12 T G M k h Dk (b) d c m m n Åp base: 100

  3. T G M k h Dk (b) d c m m n Å p • To convert from, say, kilometers to centimeters, write your quantity: 10 km • Don’t forget to include your decimal point!!! • Count the number of spaces from “k” to “c” • Move the decimal that many spaces in that direction. 10 km 100 km 1,000 km 10,000 km 100,000 km 1,000,000 cm

  4. T G M k h Dk (b) d c m m n Å p • A couple of things to keep in mind: • The letters in black differ by one decimal place • The letters in red differ by three decimal places • That “Å” has just one decimal place after “nano”

  5. Meters (m) Seconds (s) Grams (g) Liters (L) Hertz (Hz) Newtons (N) Joules (J) Watts (W) Electron Volt (eV) T G M k h Dk (b) d c m m n Å p Some base units used in Physics:

  6. Scientific Notation • To convert from regular to scientific: 24,560,000,000 kg • Move the decimal point so that the number is between 1 and 9 (count the number of places that it moved) • Round the decimal part to the second place • Slap a “x 10” at the end of the number • Give the 10 an exponent- the number of spaces you counted • If you moved the decimal to left: (+) exp. • If you moved it to the right: (-) exp. 2.4560000000 kg 2.46 x 1010 kg 2.46 kg 2.46 x 10 kg
