minute to second - How to convert ′ to ″
In precision measurements for navigation, astronomy, and surveying, the second is the next step down from the minute, offering even finer accuracy. Converting minutes to seconds is straightforward but crucial in disciplines where every fraction matters.
The Two Units in Focus
A minute (′), or arcminute, is 1⁄60 of a degree. It’s small enough to measure the apparent size of most celestial objects and fine adjustments in mapping or targeting.
A second (″), or arcsecond, is 1⁄60 of a minute, which makes it 1⁄3,600 of a degree. This incredibly small angle is used in astronomy to measure star positions, in geodesy for mapping the Earth, and even in high-precision optics.
Formula for Conversion
The formula to convert minutes to seconds is:
Seconds (″) = Minutes (′) × 60
Example:5′ × 60 = 300″

Do you know?
-
The apparent diameter of Jupiter’s largest moon, Ganymede, is about 1.7″ when viewed from Earth.
-
The Hubble Space Telescope can resolve details as small as 0.05″, far beyond the capability of the human eye.
-
In GPS surveying, accuracy can reach fractions of an arcsecond for pinpoint land measurements.
-
Astronomers use seconds to track tiny movements of stars, a technique called astrometry.
Seconds That Mapped the Stars
In the early 19th century, German astronomer Friedrich Wilhelm Bessel made one of the most significant breakthroughs in astronomy using arcseconds. He became the first to measure the distance to a star — 61 Cygni — by detecting its parallax shift of just 0.314″.
To achieve this, Bessel recorded angles in minutes, then converted them into seconds for greater precision in his calculations. This tiny measurement proved that even stars that look fixed in the sky have measurable motion relative to Earth. His work not only confirmed the vast scale of the universe but also set a new standard for observational accuracy.
The ability to convert minute readings into second precision changed astronomy forever, giving humanity its first reliable yardstick to measure the cosmos.

Precision in Practice
Converting minutes to seconds (′ to ″) is as simple as Seconds = Minutes × 60, but its applications span from charting the night sky to defining property boundaries on Earth.
