## Prompt

How many kilometers are in 100 miles? Show the conversion factor and cite a source for it.

## Response

100 miles equals about 161 km – I'll pull the exact mile-to-kilometer factor with a cited source.

100 miles is **160.934 kilometers**.

### Conversion factor

The standard conversion factor is:

> **1 mile = 1.60934 kilometers**

The more precise international definition is:

> **1 mile = 1.609344 kilometers**

Formula:

> **kilometers = miles × 1.609344**
> 
> Or commonly: `Value in kilometers = value in miles × 1.60934`

### Calculation for 100 miles

\[ 100 \times 1.60934 = 160.934 \text{ km} \]

Using the exact factor:

> **100 Miles = 160.934 Kilometers**
> *100 mi × 1.609344 = 160.934 km*

So rounded:
* **160.93 km** using 1.6093
* **160.9344 km** using 1.609344

Do you want me to convert that to meters or calculate fuel/time for that distance?
