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 = 88.1 m/s
  • Speed = 8.81 * 101 m/s (scientific)
  • Speed = 88.07 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 = 317 040 m/hr
  • Speed = 289 ft/sec
  • Time

  • Time = 3 600 secs = 1.0 hrs
  • = 3.6 * 103 sec(s)
  • = 60 min(s)
  • = 1 hr(s)
  • Speed x Time = Distance

  • Distance = 317 040 meter
  • = 1.04 * 106 ft
  • = 346.72 * 103 yard
  • = 317.04 * 103 m
  • = 317.04 km
  • = 197 mile
  • = 171.19 nautical mile
