SI Prefixes: When setting up a conversion factor to or from a base unit, use 1 for the prefixed unit and the power of 10 in front of the base unit. Example: 1 mg = 10-3 g; 1 kg = 103 g. Enter 103 in your calculator by typing 1 E 3 (using a button labeled E, EE, or EXP).
When setting up a conversion factor to or from a base unit, use 1 for the prefixed unit and the power of 10 for the base unit. Example: 1 mg = 10-3 g; 1 kg = 103 g. Give all answers in scientific notation. Practice setting these up as dimensional analysis conversions with cancelling units.
SI Prefixes: pico = p = 10−12 milli = m* = 10−3 kilo = k* = 103 (* = memorize) nano = n = 10−9 micro = = 10−6 centi = c* = 10−2 deci = d = 10−1 mega = M = 106 giga = G = 109. Give all answers in scientific notation. A. Conversions to and from base unit (no prefix).
SI Units Scientists all over the world use the same system of units so they can communicate information clearly. This system of measurement is called the International System of Units (SI). Metric measurement is based on the number ten and makes calculations with the system relatively easy.
