s =
Number of seconds with any necessary decimal required to sprint 40 yards
mi =
Miles per Hour equivalent of dash speed
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.
The amount of time a person or object takes to travel 40 yards can easily be converted to miles per hour with the simple formula below. Please consider the discussion of some limitation following the formula.
mph = 3600 / (seconds * 44)
The major assumption with this formula is that all subsequent forty yard intervals in a mile (44 intervals) will be covered in the same amount of time.
Most users of this calculator will likely be interested in converting their 40-yard dash times in football drills to miles per hour. Consider that during the forty yard dash there is an acceleration period so a person will not be running a constant speed, also it is not a sustainable pace to run for an entire mile. Therefore this is a largely theoretical calculation for the interest of comparison.
A person's maximum speed measured at an instance in time will likely be higher.
To Calculate miles per hour a distance and time is required. Since the distance is set at 40 yards we only need a time to complete the calculation.
If a running back has a 40-yard dash time of 4.5 seconds what would this be in miles per hour?
A 40-yard dash completed in 4.50 seconds would be about 18.18 miles per hour (mph), after rounding to two decimals. Convert 18.18 miles per hour to kilometers per hour using the online converter.
If a wide receiver runs a 40-yard dash in 4.45 seconds what is the theoretical speed in miles per hour?
A wide receiver running 40-yards in 4.45 seconds would run about 18.39 miles per hour if they maintained the 40-yard pace. Answer rounded to two decimals.
Convert miles per hour to other speeds
