Gradians (gon) to Revolutions (rev) Conversion
Gradians
The gradian (gon), also written grad, is a unit of angle that divides a full circle into exactly 400 equal parts, making a right angle exactly 100 gradians. Introduced during the French Revolution as part of the metric system reforms of the 1790s, the gradian was intended to decimalise angular measurement the way the metre decimalised length. It is still used in land surveying, civil engineering, and military mapping in parts of continental Europe — particularly France, the Netherlands, and Sweden — where its decimal relationship with right angles simplifies triangulation calculations.
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.
