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-9 Terameter (Tm).

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 terameter is a unit of length equal to 10¹² meters, or one trillion meters (one billion kilometers).
1 Tm = 10¹² m = 10⁹ km = 6.685 AU.
To convert Tm to AU: multiply by 6.685. To convert Tm to km: multiply by 10⁹.
Expressing outer solar system distances in metric form, though AU is standard.
One light-hour is approximately 1.08 Tm. The distance to Pluto's orbit is roughly 5.9 Tm.
Confusing tera (10¹²) with other large prefixes. Remember: tera comes after giga in the SI scale.
Think of the outer solar system: Saturn is about 1.4 Tm from the Sun, a good mental anchor.
