  1. Understanding Metric Conversions Metric Prefixes

  2. Prefixes Larger Than Base • kilo • hecto • deca

  3. Prefixes Smaller Than Base • deci • centi • milli

  4. kilo • The prefix kilo means 1000 • A kilo is one thousand times bigger than the base unit • Therefore, a kilogram is 1000 grams, a kilolitre is 1000 litres and a kilometre is 1000 metres

  5. hecto • The prefix hecto means 100 • A hecto is one hundred times bigger than the base unit • Therefore, a hectometre is 100 metres

  6. deca • The prefix deca means 10 • A deca is ten times bigger than the base unit • Therefore a decagram is 10 grams

  7. deci • The prefix deci means tenth • A deci is 10 times smaller that the base unit • Therefore, a decimetre is one-tenth of a metre or you need 10 decimetres to make a metre

  8. centi • The prefix centi means one-hundredth • A centi is 100 times smaller than the base • Therefore, a centimetre is one-hundredth of a metre or you need 100 centimetres to make a metre

  9. milli • The prefix milli means one-thousandth • A milli is 1000 times smaller than the base unit • Therefore, a milligram is one-thousandth of a gram or you need 1000 milligrams to make a gram

  10. Making Metric Conversions • Notice the unit the measure is in • Notice the unit you want to change to • How many movement do you need to make and in what direction • Move you decimal the necessary movements • Rewrite measure indicating the new unit
