Metric units are used almost universally and very handy (pun intended, since it is a base ten system... you know because that's the number of

fingers most of us are blessed with!). Since all metric prefixes are powers of 10, you just have to multiply or divide by a power of ten when

converting from, for example, a*centimeter* to *kilometer*. You just need to be able to use the following conversions noted below in the tables.

Here you would divide the number of centimeters, by 100,000 , since there are 100 centimeters in a meter, and 1,000 meters in a kilometer.

Therefore there are 100,000 (100 times 1,000) centimeters in 1 kilometer.

Units of Length | |

10 millimeters (mm) | = 1 centimeter (cm) |

10 centimeters | = 1 decimeter (dm) = 100 millimeters |

10 decimeters | = 1 meter (m) = 1000 millimeters |

10 meters | = 1 dekameter or decameter (dam) |

10 dekameters | = 1 hectometer (hm) = 100 meters |

10 hectometers | = 1 kilometer (km) = 1000 meters |

width="175">= 1 centigram (cg)

Units of Mass | |

10 centigrams | = 1 decigram (dg) = 100 milligrams |

10 decigrams | = 1 gram (g) = 1000 milligrams |

10 grams | = 1 dekagram (dag) |

10 dekagrams | = 1 hectogram (hg) = 100 grams |

10 hectograms | = 1 kilogram (kg) = 1000 grams |

1000 kilograms | = 1 megagram (Mg) or 1 metric ton(t) |

Units of Liquid Volume | |

10 milliliters (mL) | = 1 centiliter (cL) |

10 centiliters | = 1 deciliter (dL) = 100 milliliters |

10 deciliters | = 1 liter or litre = 1000 milliliters |

10 liters | = 1 dekaliter (daL) |

10 dekaliters | = 1 hectoliter (hL) = 100 liters |

10 hectoliters | = 1 kiloliter (kL) = 1000 liters |

Units of Area | |

100 square millimeters (mm2) | = 1 square centimeter (cm2) |

100 square centimeters | = 1 square decimeter (dm2) |

100 square decimeters | = 1 square meter (m2) |

100 square meters | = 1 square dekameter (dam2) = 1 are |

100 square dekameters | = 1 square hectometer (hm2) = 1 hectare (ha) |

100 square hectometers | = 1 square kilometer (km2) |

Units of Volume | |

1000 cubic millimeters (mm3) | = 1 cubic centimeter (cm3) |

1000 cubic centimeters | = 1 cubic decimeter (dm3) |

= 1 000 000 cubic millimeters | |

1000 cubic decimeters | = 1 cubic meter (m3) |

= 1 000 000 cubic centimeters | |

= 1 000 000 000 cubic millimeters |
