What is the unit of h?

h can represent different units, as follows:

1. h can represent the time unit hour, for example: 2h represents two hours.

2. h can represent Henry, the unit of inductance in physics, for example: 10h represents 10 Henry.

3. h can represent the unit horsepower in mechanics, for example: 100h represents 100 horsepower.

4. h can represent the symbol High on the weather map indicating high pressure or anticyclone. For example: H represents a high pressure area.

The hour is not the SI base unit of time, but an auxiliary unit of time that is coordinated with the SI base unit. Except for leap seconds, one hour is generally equal to 3600 seconds, or 60 minutes, or 1/24 of a day. Time measurement in human daily life is generally measured in hours, such as time of day, such as 8 o'clock in the morning, which is the eighth hour of the day.

The SI prefix is ??often combined with seconds to make finer divisions, such as ms (millisecond, one thousandth of a second), us (microsecond, one millionth of a second), and ns (nanosecond, one billionth of a second) Second).

Although SI prefixes can also be used to expand time, such as ks (kiloseconds), Ms (millions of seconds) and Gs (billion seconds), they are rarely used in this way. , everyone is still accustomed to using 60-based minutes, hours and 24-based days as extensions of seconds.
