Hz is short for Hertz, which is the international standard (SI) unit of frequency of an alternating current (AC) voltage. 50Hz means the voltage alternates 50 times per second, 60Hz obviously means 60 times/sec. 60Hz is the normal frequency of the incoming power lines in North America, while 50Hz is seen in many European countries. While convertors exist to use electric devices on a different voltage, convertors generally are not available to use 50Hz devices on a 60Hz power grid, or vice-versa. While some devices can be used on either, many others will not work or may even be damaged. Check with the manufacturer to be sure. Incidentally, since the unit of Hertz is named after the German physicist Heinrich Hertz, it is customary to capitalize the H. So 60Hz is considered correct, while 60hz is not.

One cycle of a 60 Hz AC (alternating current) waveform takes 1/60th of a second to complete. This means that the waveform goes through one complete cycle— from zero to its maximum positive value, back through zero to its maximum negative value, and back to zero— in 1/60th of a second.
1/60 th of a second or 0.01666667 second. 1hz or 1 Hertz means 1 complete cycle per second so 60hz means 60 complete cycles per second.
The stance phase typically takes up the most time in a normal gait cycle, accounting for about 60% of the entire cycle.
Disk rotation time can be calculated using the formula: Rotation time = (1 / RPM) * 60 seconds. RPM stands for revolutions per minute, which indicates how many times the disk spins in one minute. By taking the reciprocal of the RPM and multiplying it by 60 seconds, you can determine the time it takes for one complete rotation of the disk.
The efficiency of the Krebs cycle in terms of converting glucose into ATP is around 60%. This means that for every molecule of glucose that enters the cycle, about 60% of the energy is captured in the form of ATP. The rest of the energy is lost as heat.
It depends on the species - anywhere from 10 to 60 !
AC frequency refers to the number of complete cycles of alternating current that occur in one second. It is measured in Hertz (Hz) and determines the rate at which the direction of the current changes. In most countries, the standard AC frequency for power distribution is 50 or 60 Hz.
