Unit Explanations
Centuryc
Source UnitA century is a unit of time that represents a period of 100 years. It is commonly used in the context of historical timelines, calendar systems, and various scientific analyses of temporal data. Centuries are often denoted in ordinal form (e.g., 21st century) to signify their position in the chronological sequence. The concept of a century helps organize and categorize historical events, societal changes, and technological advancements over substantial time spans, making it a fundamental unit in both historical and modern contexts.
Current Use
Today, centuries are widely used in historical studies, literature, and societal analyses to denote significant periods of 100 years. Various disciplines, including history, sociology, and even climate science, reference centuries for organizing data, understanding trends, and making projections. The 21st century, for instance, is characterized by rapid technological advancements and globalization, while the 19th century is known for industrialization and significant social changes.
Fun Fact
The first century AD began in the year 1 and ended in the year 100.
Second of Arc"
Target UnitA second of arc, also known as an arcsecond, is a unit of angular measurement that is equal to 1/3600 of a degree or 1/60 of an arcminute. It is used primarily in fields that require precise angular measurement, such as astronomy, navigation, and mapping. An arcsecond is a small unit, reflecting the requirement for high precision in measurements of celestial objects and angles on the Earth's surface. The notation for a second of arc is usually represented by a double prime symbol ("), following the degree and arcminute symbols.
Current Use
Today, the second of arc is indispensable in astronomy for measuring the positions and movements of celestial objects with high precision. It is also used in geodesy and cartography to define the precise angular relationships between points on the Earth. Additionally, arcseconds are employed in the calibration of telescopes and other optical instruments where small angular measurements are critical.
Fun Fact
An arcsecond is roughly the angle subtended by a U.S. dime at a distance of 2.4 miles.

The concept of a century helps organize and categorize historical events, societal changes, and technological advancements over substantial time spans, making it a fundamental unit in both historical and modern contexts.
History & Origin
The concept of a century has its roots in the Latin word 'centuria', which means a group of one hundred. The ancient Romans used the term to denote a century of soldiers, and this numerical grouping was later adapted to represent years. The transition to its current use to denote years began in the Middle Ages as historians looked to structure historical events by significant intervals of time, marking the passage of eras.
Etymology: The word 'century' derives from the Latin word 'centum', meaning one hundred.

💡 Fun Facts
- •The first century AD began in the year 1 and ended in the year 100.
- •There is no year 0 in the Gregorian calendar; hence, the 1st century spans from AD 1 to AD 100.
- •The 21st century is often humorously referred to as the 'digital century' due to technological advancements.

The notation for a second of arc is usually represented by a double prime symbol ("), following the degree and arcminute symbols.
History & Origin
The concept of dividing a circle into degrees and further into minutes and seconds dates back to ancient Babylonian astronomers, who used a sexagesimal (base-60) number system. The division of a degree into 60 parts, known as minutes, and each minute into 60 parts, known as seconds, allowed for more precise measurement and calculation of angles in the study of celestial bodies. This system became widespread with the work of Greek and later Islamic scholars, who advanced astronomical knowledge and navigation.
Etymology: The term 'second' in this context comes from the Latin 'secunda', meaning 'second division' or 'second order', referring to its place in the hierarchical division of degrees.
Current Use
Today, the second of arc is indispensable in astronomy for measuring the positions and movements of celestial objects with high precision. It is also used in geodesy and cartography to define the precise angular relationships between points on the Earth. Additionally, arcseconds are employed in the calibration of telescopes and other optical instruments where small angular measurements are critical.
💡 Fun Facts
- •An arcsecond is roughly the angle subtended by a U.S. dime at a distance of 2.4 miles.
- •The Hubble Space Telescope can resolve images with an angular resolution of about 0.05 arcseconds.
- •In one parsec, which is a unit of astronomical distance, a star would have a parallax angle of one arcsecond.
