## Prompt

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

## Response

100 miles equals **160.9344 kilometers** (about 160.93 km). The conversion is exact: the international mile is defined as precisely 1.609344 kilometers [unit-convert.com](https://unit-convert.com/length/miles-to-km.htm).

## Conversion Factor

- **1 mile = 1.609344 km** (exactly 1,609.344 meters, per the 1959 international agreement)
- **1 km ≈ 0.621371 miles**

## Calculation

\[ 100 \text{ mi} \times 1.609344 \frac{\text{km}}{\text{mi}} = 160.9344 \text{ km} \]

Because the factor is a defined constant rather than a measured approximation, the result involves no rounding error [mileconverter.com](https://mileconverter.com/mile-to-kilometer/). For quick mental math, multiplying miles by 1.6 gets you within 1% of the true value [calcintel.com](https://www.calcintel.com/calculator/miles-to-km).

Would you like a similar breakdown for a different distance or the reverse conversion (km to miles)?
