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) = 0.000001609344 Gigameter (Gm).

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 gigameter is a unit of length equal to 10⁹ meters, or one billion meters (one million kilometers).
1 Gm = 10⁹ m = 10⁶ km = 0.00668 AU.
To convert Gm to km: multiply by 1,000,000. To convert Gm to AU: divide by 149.598.
Describing distances between planets in a compact metric format, though AU is preferred.
Light travels about 0.3 Gm per second (299,792 km/s ≈ 0.3 Gm/s).
Mixing up Gm with Gb (gigabyte) in mixed technical contexts. Context matters for the prefix 'giga'.
The Sun is ~150 Gm away from Earth — this is a useful anchor for the gigameter scale.
