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

5. 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)

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

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

8. 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)
