Three-Quarter Court Sprint to Miles per Hour Calculation:

  •  s =
    Sprint Seconds

    Measured time to run 75 feet, the standard three-quarter-court sprint distance.

  • mph =
    Miles per Hour

    Average speed in miles per hour across the sprint.

  • kph =
    Kilometres per Hour

    Average speed in kilometres per hour across the sprint.

  • Decimals

    Choose the number of decimals to show in your answer. This is also known as significant figures. Select an appropriate amount of significant figures based on the precision of the input numbers.

Three-Quarter Court Sprint to Miles per Hour Formula

The standard basketball three-quarter-court sprint covers 75 feet. Convert that fixed distance and the measured sprint time into an average speed.

mph = 3600 / (seconds x 70.4)

kph = mph x 1.609344

The result is an average speed over the whole sprint rather than an instant peak speed.

Three-Quarter Court Sprint to Miles per Hour Variables

Sprint Seconds
The measured time for the 75-foot sprint.
Miles per Hour
Average sprint speed expressed in miles per hour.
Kilometres per Hour
The same average sprint speed expressed in kilometres per hour.

How the Calculation Works

  1. Use the fixed sprint distance of 75 feet.
  2. Divide by the measured time to get feet per second.
  3. Convert that speed to miles per hour, then to kilometres per hour.

Three-Quarter Court Sprint to Miles per Hour Example

What average speed corresponds to a 4-second three-quarter-court sprint?

  • mph = 3600 / (4 x 70.4)
  • mph = 12.78
  • kph = 20.57

A 4-second three-quarter-court sprint corresponds to about 12.78 mph or 20.57 kph on average.
