Si unit of rotational speed

WebbThe acceleration is directed radially toward the centre of the circle. The centripetal acceleration ac has a magnitude equal to the square of the body’s speed v along the curve divided by the distance r from the centre of the circle to the moving body; that is, ac = v2 / r. Centripetal acceleration has units of metre per second squared. http://www.claredot.net/en/sec-Conversions/conv-rotation-speed.php
