Kilogram (kg) Kelvin (K) Ampere (A) What are they? Time Length/distance Mass Temperature Electric current Derived Units: Volume 1 cm3 = 1 mL

4 SI Conversion milli- m 10-3 centi- c 10-2 kilo- k 103 mega- M 106
giga- G 109 Examples

5 Scientific Notation Why use it? Format
Easier to write really small or large numbers Format ? x 10n ? = number between 1 and 10 n = positive exponent (for large numbers) n = negative exponent (for small numbers)
