## Conversion Factor and Calculation

The precise conversion factor from miles to kilometers is:
\[ 1 \text{ mile} = 1.609344 \text{ kilometers} \] [RapidTables](https://www.rapidtables.com/convert/length/mile-to-km.html?x=100).

To convert 100 miles to kilometers, multiply the number of miles by the conversion factor:
\[ 100 \text{ miles} \times 1.609344 \frac{\text{km}}{\text{mile}} = 160.9344 \text{ kilometers} \] [unit-convert.com](https://unit-convert.com/length/miles-to-km.htm).

Conversely, you can also use division with the reciprocal value, where one kilometer is approximately 0.6213711922 miles:
\[ \text{Kilometers} = \text{Miles} \div 0.6213711922 \] [quickunitconverter.com](https://quickunitconverter.com/length/100-miles-to-km/).

This conversion factor was established by an international agreement in 1959 to standardize the relationship between imperial and metric units [mileconverter.com](https://mileconverter.com/mile-to-kilometer/).

Do you need to convert a different number of miles to kilometers?
