Kilometers to Miles

This formula converts a distance measured in kilometers into the equivalent distance in miles by multiplying by 0.6214. The number 0.6214 comes from the relationship between the two units: 1 kilometer is about 0.6214 miles, so the calculation scales the distance into a smaller unit. It works because kilometers and miles both measure length, just using different size units.

Use this when you need to change a metric distance into a U.S. customary distance, such as for travel distances, road signs, or sports and fitness tracking. It is also useful in science, geography, and everyday comparisons between metric and imperial measurements.

• Using 1.61 instead of 0.6214, which reverses the conversion
• Forgetting to multiply the kilometers and instead adding the conversion factor
• Rounding too early and losing accuracy in the final answer
