## Meter (m) |
## The standard unit of the metric system |

## Decimeters (dm) |
## 1/10th of a meter or 0.1 m = 10^-1m |

## Centimeters (cm) |
## 1/100th of a meter, or 0.01 m = 10^-2m |

## Millimeters (mm) |
## 1/1000th of a meter, or 0.001 m = 10^-3m |

## Micrometers (mum) |
## 1/1,000,000th of a meter, or 0.000001 m = 10^-6m |

## Nanometers (nm) |
## 1/1,000,000,000th of a meter, or 0.000000001m = 10^-9m |

## Angstroms (A) |
## 1/10,000,000,000th of a meter, or 0.0000000001m = 10^-10m |
