The first time the term **Mile** was used to denote distance was in Ancient Rome. In this case, the earth mile was equivalent to 1000 steps (from the Latin, mille passus) given by the Centurion. Obviously, this measure was not accurate, since it depended on the size of the centurion's legs. In the case of the sea or nautical mile that came later, its calculation is much more scientific. Knowing that the equator line measures approximately 40,000 km, this value was divided by the 360º that this line does when circumventing the planet and then by 60 to convert to minutes. Thus a correspondence was established between the measurement of the equator and the sea mile.

The word **Kilometer** is a combination of the prefix "kilo" (meaning thousand) with the word meter. That is the reason why one kilometer equals exactly one thousand meters. In spite of this, it should be noted that the abbreviation for the word kilometer is "km". To finish, never place the plural in the kilometer symbol, that is, whether it is 1 km or 8 km, the abbreviation should always appear in the singular.

`km=(mi)/0.62137`

If you do not wish to use our converter, you can always choose to perform the mathematical conversion operations manually. To do this, simply follow the following steps:

- Replace the variable
**mi**with the value in miles that you want to convert. - Carry out mathematical operations, respecting priorities.
- Get the final value of km with the rounding you want.

miles to km | miles to km |
---|---|

1 mi = 1,6093 km | 35 mi = 56,3271 km |

2 mi = 3,2187 km | 40 mi = 64,3739 km |

3 mi = 4,8280 km | 45 mi = 72,4206 km |

4 mi = 6,4374 km | 50 mi = 80,4674 km |

5 mi = 8,0467 km | 60 mi = 96,5608 km |

10 mi = 16,0935 km | 70 mi = 112,6543 km |

15 mi = 24,1402 km | 80 mi = 128,7478 km |

20 mi = 32,1869 km | 90 mi = 144,8412 km |

25 mi = 40,2337 km | 100 mi = 160,9347 km |

30 mi = 48,2804 km | 500 mi = 804,6735 km |
