Common Conversions

1 km/h = 0.28 m/s = 0.62 mph

1 m/s = 3.6 km/h = 2.24 mph

1 mph = 1.61 km/h = 0.45 m/s

1 hour = 60 minutes = 3600 seconds

1 km = 1000 m = 0.62 miles

About Speed, Distance & Time

Speed, distance, and time are related by a simple formula: Speed = Distance / Time. This relationship allows you to calculate any one of these variables if you know the other two.

Formulas

  • Speed = Distance ÷ Time - Calculate how fast something is moving
  • Distance = Speed × Time - Calculate how far something will travel
  • Time = Distance ÷ Speed - Calculate how long a journey will take

Speed Units

  • Kilometers per hour (km/h) - Common for road speeds in most countries
  • Meters per second (m/s) - Standard unit in physics
  • Miles per hour (mph) - Used in the US, UK, and some other countries
  • Feet per second (ft/s) - Used in some engineering applications

Practical Applications

  • Travel Planning: Calculate arrival times or required speeds for journeys
  • Sports: Measure athletic performance in running, cycling, swimming, etc.
  • Physics: Solve motion problems in academic or professional settings
  • Navigation: Plan routes and estimate travel durations
