Conversion Definitions
Miles: A mile is a unit of distance used mainly in the United States and United Kingdom. It equals 5,280 feet or 1,760 yards. One mile is defined exactly as 1,609.344 meters in the metric system. It is used to measure longer distances like road lengths and travel distances.
Kilometers (km): Kilometer is a metric unit of length equal to 1,000 meters. It is widely used worldwide for measuring distances on roads, maps, and in travel. 1 kilometer equals approximately 0.6214 miles. Kilometers are part of the International System of Units.
Conversion FAQs
Why do we multiply miles by 1.60934 to get kilometers?
The number 1.60934 is the exact length of one mile expressed in kilometers. Since miles and kilometers measure the same thing (distance), to change from one unit to the other, we multiply by the ratio that relates their lengths. Multiplying by 1.60934 converts miles into the longer kilometer unit properly.
Is it okay to round 1.60934 to 1.6 when converting miles to kilometers?
Rounding 1.60934 to 1.6 gives a rough estimate but introduces slight error. For some everyday uses, 1.6 is close enough and simpler to calculate mentally. However, for accuracy, especially in scientific or precise navigational contexts, it’s better to use 1.60934.
