Standards of Measurement Section 1.2

Measurement Standard- exact quantity people agree to use for comparison Unit- description of what standard was used SI system- international system of units Allows easy communication between scientists g, m, L, s, A, K, mol - base units- unit by itself

Metric Prefixes Giga- 1,000,000,000 G Mega- 1,000,000 M Kilo- 1,000 k Hecto- 100 h Deca – 10 da Base Unit Deci- 0.1 d Centi- 0.01 c Milli- 0.001 m Micro- 0.000001 μ

Metric Conversions Conversion factor- ratio equal to 1 that can be used to convert between units Volume- space occupied by an object Mass- amount of matter in an object Density- mass per unit volume- reason same volume may have different mass Derived unit- combinations of base units g/ml

Temperature Temperature- measure of average KE of molecules Celsius Fahrenheit Kelvin 0 K = -273.15oC K = oC + 273.15 oC = K -273.15
