Distance: Speed Conversion Calculator

This calculator helps you estimate the distance travelled after a certain time of constant speed. It also converts to alternative speed units: mile/hr, km/h, m/s, mach, ...

Speed

METRIC (DECIMAL)

Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude.

  • Speed = 25.4 m/s
  • Speed = 2.54 * 101 m/s (scientific)
  • Speed = 25.43 m/s (engineering)
    • IMPERIAL

    In the USA and UK, the older Imperial system is used, where things are measured in feet, inches and pounds.

  • Speed = 91 560 m/hr
  • Speed = 83.4 ft/sec

    • Time

  • Time = 604 800 secs = 1.0 wks
  • = 604.8 * 103 sec(s)
  • = 10.08 * 103 min(s)
  • = 168 hr(s)
  • = 7 day(s)
  • = 1 wk(s)

    • Speed x Time = Distance

  • Distance = 15 382 000 meter
  • = 15.38 * 103 km
  • = 9.56 * 103 mile
  • = 8.31 * 103 nautical mile

    • Examples

  • Car driving 24 hours at 120 km/h = 2880 km
  • 1 year x speed of light = 1 light-year
  • Garden snail on the move for 24h = 1.12 km
  • Cheetah at top speed for 30 seconds = 993 m
  • Koenigsegg CCR at 242 mph for 1 minute = 6.49 km
  • Usain Bolt at 10.44 m/s for 9.58 secs = 100 m
