# Convert Petahertz to Millihertz

Please provide values below to convert petahertz [PHz] to millihertz [mHz], or *vice versa*.

### Petahertz to Millihertz Conversion Table

Petahertz [PHz] | Millihertz [mHz] |
---|---|

0.01 PHz | 1.0E+16 mHz |

0.1 PHz | 1.0E+17 mHz |

1 PHz | 1.0E+18 mHz |

2 PHz | 2.0E+18 mHz |

3 PHz | 3.0E+18 mHz |

5 PHz | 5.0E+18 mHz |

10 PHz | 1.0E+19 mHz |

20 PHz | 2.0E+19 mHz |

50 PHz | 5.0E+19 mHz |

100 PHz | 1.0E+20 mHz |

1000 PHz | 1.0E+21 mHz |

### How to Convert Petahertz to Millihertz

1 PHz = 1.0E+18 mHz

1 mHz = 1.0E-18 PHz

**Example:** convert 15 PHz to mHz:

15 PHz = 15 × 1.0E+18 mHz = 1.5E+19 mHz
