Road signs, marathon distances (42.195 km), GPS navigation, geographic mapping, and aviation flight distances.
A marathon is 42.195 km. The circumference of Earth is approximately 40,075 km at the equator.
Assuming 1 km = 1 mile. A kilometer is only about 62% of a mile. Also, speed: 100 km/h ≈ 62 mph, not 100 mph.
Quick approximation: multiply km by 0.6 to estimate miles, or multiply miles by 1.6 for km.
