called the frequency of rotation or revolutions per minute (RPM). This measure is commonly used in physics and engineering to describe the speed of rotating objects.
The most widely used measurement of this sort is "rpm" or "revolutions per minute". This measures the amount of full 360 degree rotations happen over a 60 second time period.
The number of revolutions the disk in a kWh meter needs to make to produce a read increase of one unit (1 kWh) is 1000 divided by the disk constant. The disk in a meter with a 7.2 constant (Kh = 7.2) will have to make 138 and 8/9 revolutions to make the right most dial in the meter increase its read by one unit.
The unit used to count or measure quantities on the number of time zones axis is simply "number of time zones." This unit represents the count of distinct time zones around the world.
One kilowatt-hour (kWh) is a unit of energy, not rotation. It represents the amount of energy consumed when one kilowatt of power is used for one hour. The concept of rotations does not directly translate to kWh.
The SI unit for time is the second.
A unit of measurement, a number indicating the quantity, and a scale or reference to provide context.
