Angular rate

Converts turn and rotation rates: degrees per second or per minute, radians per second, revolutions per minute, and slow rates such as arcseconds or milliarcseconds per year. Drone builders read gyro and motor specs with it, and geodesists use it for plate and frame rotation rates. Start with the angular rate converter. Pitfall: many gyros and code libraries report radians per second while datasheets quote degrees per second. One radian per second is 57.29578 degrees per second, so a mix-up is hard to miss but easy to make.
