There is no equivalence.
Per square hour is a measure with dimension [T-2] - which may be used, for example, when measuring acceleration. A second is a measure of time with dimension [T]. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid without some addition information.
To convert miles per hour to seconds, you need to know the distance covered in a specific time period. Miles per hour is a unit of speed, while seconds are a unit of time. Without additional information, it is not possible to directly convert 126 miles per hour into seconds.
You divide by 3600 - since an hour has 3600 seconds.
k seconds per mile = 3600/k miles per hour.
To convert miles per hour to feet per second multiply by 5280 (feet in a mile) and then divide by 3600 (seconds in an hour).
139 yards per 25.75 seconds is probably 11.04 miles/hour.
Multiply by seconds.
just divide your km/h by 3600, the number of seconds in an hour.
Converting 7.41ms2 to kmh2 gives 96033.6 km/h2. This is because 1ms2 or meter per square seconds is equivalent to 12960 km/h2 or kilometer per square hour.
1 fluid ounce per second = 28.12500 gallons per hour
Use the facts that there are 5,280 feet per mile and 3600 seconds per hour.
300 feet per 2.92 seconds = ~70.05 (70.0498132) mph
1 609.344 meters = 1 mile3600 secs = hour
