I believe it is RPM's (Reps Per Minute)
4 km/per hour
Divide the litres per minute by 4.55
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.
The hour hand = 24 rotations per day. The minute hand = 24 x 60 = 1,440 rotations per day. The second hand = 24 x 60 x 60 = 84,400 rotations per day. That;s a total of 87,864 rotations for all three pointers.

A typical windmill rotates at around 10 to 25 rotations per minute, although this can vary depending on the design and wind conditions.
1500 rotations per minute. That's crank speed.
Divide the litres per minute by 4.55
Strokes per minute is not a unit of capacity and hence, there is no correspondence with gallons per minute. Strokes per minute is comparable with rotations or revolutions per minute. SPM is normally used for reciprocating machines, to define the speed. A. R. Pathak
There is not a relationship without more information.
Cubic feet per minute x 28.3168 = liters per minute
Multiply liters per minute by 0.0353146667 to get cubic feet per minute.
Multiply meters per minute by 3.28 to get feet per minute.
The hour hand = 24 rotations per day. The minute hand = 24 x 60 = 1,440 rotations per day. The second hand = 24 x 60 x 60 = 84,400 rotations per day. That;s a total of 87,864 rotations for all three pointers.
