Conversion FAQs

Why does one mile equal 1.60934 kilometers?

The mile was originally defined based on Roman measurements, while the kilometer comes from the metric system, based on meters. Through international agreement and precise measurement, the exact conversion factor 1.60934 was established to maintain accuracy between the two units.

Can I convert miles to kilometers by just doubling the miles?

No, doubling miles gives an approximate conversion but is not accurate. One mile equals about 1.60934 kilometers, so doubling would result in 2 kilometers per mile, which overestimates the distance. Using the exact conversion factor is necessary for precision.

Is the mile to kilometer conversion factor always the same?

Yes, the conversion factor 1.60934 is a fixed constant agreed upon internationally. It does not change with location or context, so you can reliably use this factor for any mile-to-kilometer conversion.
