Miles to Kilometers Formula
To convert miles to kilometers, you multiply the number of miles by 1.60934.
Kilometers (km) = Miles (mi) × 1.60934
Conversely, to calculate miles from kilometers, you divide the kilometers by 1.60934 (which is the same as multiplying by roughly 0.621371).
Miles (mi) = Kilometers (km) ÷ 1.60934
Example
If your GPS says your destination is 10 miles away:
10 × 1.60934 = 16.0934 km
Therefore, 10 miles is approximately 16.1 kilometers.

Duration Formula
To calculate how long it takes to travel a certain distance, you divide the distance by your speed.
Time (hours) = Distance ÷ Speed
Example
If you are traveling 50 miles at a speed of 60 mph:
50 ÷ 60 = 0.833 hours
To convert this to minutes, multiply the decimal by 60 (0.833 × 60 ≈ 50 minutes). Therefore, it takes about 50 minutes.
