SI Measurements (also known as “metric system”) “SI” stands for “System International” or “International System of Measurement”

What about it? –Common Language for scientists –Based on units of 10 –Multiply or divide to go up or down when converting units –Prefixes determine “how much” of a unit SI Measurements (also known as “metric system”)

Important BASE units to remember: METERS = m (measures distance or length) ruler/meterstickMeasure with ruler/meterstick

LITERS = L (measures volume — how much space something takes up) graduated cylinder/beakerMeasure with graduated cylinder/beaker Or with a ruler (length x height x width)Or with a ruler (length x height x width)

g GRAMS = g (measures mass) triple beam balance/electronic balanceMeasure with triple beam balance/electronic balance

o C o CELSIUS = o C (measures temperature) thermometerMeasure with thermometer

Important PREFIXES to remember: 1000 k = kilo- (means “1000”) 100 h = hecto-(means “100”) 10 d = deca-(means “10”) BASE UNIT (gram, meter, liter) 1/10” or 0.1 d = deci-(means “1/10” or 0.1) 1/100 c = centi- (means “1/100” or.01) 1/1000 m = milli- (means “1/1000” or.001)
