Revolutions (rev) to Arcseconds (″) Conversion
Revolutions
A revolution (rev) is a unit of angle equal to exactly one complete rotation — 360 degrees, 2π radians, or 400 gradians. It is used in engineering and mechanics to describe rotational motion, most commonly as revolutions per minute (RPM) — the standard measure of rotational speed for engines, motors, turbines, and drill bits. A car engine at idle typically runs at 700–900 RPM; at highway cruising speed, 2,000–3,000 RPM. In astronomy, the orbital period of Earth is exactly one revolution around the Sun per year.
Arcseconds
The arcsecond (″, Unicode U+2033) is a unit of angle equal to exactly 1/3,600 of a degree, or 1/60 of an arcminute (approximately 4.848 × 10⁻⁶ radians). It is the standard unit of angular resolution in astronomy: the Hubble Space Telescope achieves a resolution of approximately 0.05 arcseconds; the nearest star, Proxima Centauri, has a parallax of 0.769 arcseconds — the basis for measuring its distance. In geodesy, GPS coordinates are routinely recorded to sub-arcsecond precision, corresponding to positional accuracy of approximately 30 metres on Earth's surface.
