Visual representation of 677 kph compared to other speeds:

Speed is the rate at which an object moves in a specific direction. The two most common units for measuring speed are:

  • Kilometers per hour (kph): Used in most countries worldwide that follow the metric system.
  • Miles per hour (mph): Primarily used in the United States and the United Kingdom.

The conversion between these units is based on the relationship between kilometers and miles:

1 mile = 1.60934 kilometers

Therefore:

  • To convert kph to mph: mph = kph × 0.6214
  • To convert mph to kph: kph = mph × 1.6093

677 kph is a very high speed, typically achieved by:

  • High-performance sports cars and supercars
  • High-speed trains like the Japanese Shinkansen or French TGV
  • Formula 1 racing cars on straightaways
