Unit Explanations
Hourh
Source UnitAn hour is a standardized unit of time that is conventionally understood as consisting of 60 minutes, or 3600 seconds. It is a non-SI unit that is accepted for use with the International System of Units (SI). The hour is widely used in daily life to schedule events, plan activities, and coordinate across various domains including work, transportation, and communication. It plays a crucial role in timekeeping and is fundamental to the division of the day into manageable portions.
Current Use
Today, the hour is ubiquitously used to denote time intervals in daily life, commerce, transportation, and technology. It is critical for scheduling meetings, coordinating international communications, and managing day-to-day activities. The hour is a fundamental unit in time management and is used extensively in digital and analog clocks.
Fun Fact
The hour was initially divided into 12 parts by the Egyptians.
Minute of Arc'
Target UnitA minute of arc, often referred to simply as a 'minute', is a unit of angular measurement equal to 1/60th of one degree. It is denoted by the prime symbol ('). The unit is used in fields such as astronomy, navigation, and engineering to measure small angles with precision. One minute of arc is further subdivided into 60 arcseconds, making it a crucial component in the finer division of angles. It is not an SI unit but is widely used in practical applications due to its straightforward relationship with degrees.
Current Use
Today, the minute of arc is used predominantly in fields requiring precise angular measurements. In astronomy, it helps in locating stars and celestial phenomena. In navigation, it assists mariners and pilots in plotting courses. Engineering applications often utilize minutes of arc in precision measurements and design. Despite the advent of modern technology, these traditional methods remain integral to accurate calculations.
Fun Fact
A full circle has 21,600 minutes of arc.

Definition
An hour is a standardized unit of time that is conventionally understood as consisting of 60 minutes, or 3600 seconds. It is a non-SI unit that is accepted for use with the International System of Units (SI). The hour is widely used in daily life to schedule events, plan activities, and coordinate across various domains including work, transportation, and communication. It plays a crucial role in timekeeping and is fundamental to the division of the day into manageable portions.
History & Origin
The concept of an hour dates back to ancient Egyptian times, where the day was divided into 12 parts, with each corresponding to the movement of the sun across the sky. This division was later refined by the Babylonians, who used a base-60 system to divide an hour into 60 minutes, and a minute into 60 seconds. The modern definition of an hour as precisely 3600 seconds was established in the 20th century, aligning with the atomic definition of the second.
Etymology: The word 'hour' originates from the Latin 'hora', which in turn was derived from the Greek word 'hōra', meaning a period of time.

History & Origin
The concept of dividing a circle into 360 degrees has ancient origins, likely stemming from the Sumerians and Babylonians around 3000 BCE, who used a base-60 number system. The minute of arc as a subdivision of the degree emerged from this system as a practical method for detailed angular measurement. This division allowed for more precise calculations necessary in fields like astronomy and navigation.
Etymology: The term 'minute' comes from the Latin 'pars minuta', meaning 'small part'.
