What is a quadrant in angle measurement?

A quadrant is an angular region equal to one quarter of a full circle, corresponding to 90 degrees or π/2 radians.

What is a second ["] in angular units?

A second (arcsecond) is an angular measurement equal to 1/3600 of a degree, used for very small angles in fields like astronomy and surveying.

Why convert from quadrant to seconds?

Converting from quadrant to seconds helps translate large angular sectors into precise smaller units essential for detailed measurements in astronomy, optics, and surveying.
