hour
Definition: An hour (symbol: h) is a unit of time conventionally defined as 1/24 of a day and 3,600 seconds. In Coordinated Universal Time, a negative or positive leap second may be incorporated to keep the hour within 0.9 seconds of universal time, making an hour either 3,599 or 3,601 seconds in some cases.
History/origin: The term "hour" is derived from the Anglo-Norman "houre," which was in use around the 13th century. There have been many definitions of the hour throughout history based on culture or region, such as the hour being divided into 1/12 of a period daylight or darkness. It is believed that the custom of dividing the cycle of day and night into 24 periods began with the ancient Egyptians.
Current use: The hour is used globally as a unit of time. Most forms of employment require a certain number of hours worked per day, with compensation being based on the measured or expected hours worked. Durations starting from 30 minutes (half an hour) are commonly used colloquially.
millisecond
Definition: A millisecond (symbol: ms) is a unit of time based on the SI (International System of Units) base unit of time, the second, and is equal to one-thousandth of a second.
History/origin: The millisecond is based on the SI unit of second, making use of the SI prefix of "milli," meaning 1/1000.
Current use: The millisecond is used to measure smaller durations of time such as frequency of a soundwave, response time of LCD monitors, the wing flap of insects and birds, and time delays, among many others.
