To convert miles to km: multiply by 1.60934. To convert km to miles: multiply by 0.621371.
1 mi = 5,280 ft = 1,760 yd = 1,609.344 m = 1.609344 km.
For example, 1 Mile (mi) = 1.609344e-12 Petameter (Pm).

The mile is a unit of length equal to 5,280 feet, 1,760 yards, or exactly 1,609.344 meters.
1 mi = 5,280 ft = 1,760 yd = 1,609.344 m = 1.609344 km.
To convert miles to km: multiply by 1.60934. To convert km to miles: multiply by 0.621371.
Highway distances, speed limits (mph), running races (1-mile run), and property boundary descriptions.
A 4-minute mile was once thought impossible. Roger Bannister broke the barrier in 1954 with a time of 3:59.4.
Confusing statute miles with nautical miles (1 nmi = 1.852 km vs 1 mi = 1.609 km). They're different units.
Quick km↔mi: Fibonacci numbers approximate the ratio! 5 mi ≈ 8 km, 8 mi ≈ 13 km, matching the 1.6 ratio.
The petameter is a unit of length equal to 10¹⁵ meters, or about 0.1 light-years.
1 Pm = 10¹⁵ m ≈ 0.1057 light-years ≈ 0.0324 parsecs.
To convert Pm to light-years: divide by 9.461. To convert Pm to parsecs: divide by 30.857.
No practical everyday applications. Would describe distances to nearby stars in metric.
1 light-year ≈ 9.46 Pm. The Oort Cloud extends to roughly 15,000 Pm from the Sun.
Case sensitivity is critical: Pm (petameter) vs. pm (picometer) differ by a factor of 10²⁷!
Remember: 1 light-year ≈ 9.46 Pm, so a few Pm is a fraction of the distance to the nearest star.
