In principle you can, but if you want to use it in formulas together with radians and seconds (e. g. to calculate the kinetic energy of a rotation object) you need a unit conversion.avito009 said:Why can we not just use rpm as unit of measure of angular velocity?
The formula for converting RPM (revolutions per minute) to units depends on the type of unit being used. However, the general formula is: Units = RPM * (60/360) * (2πr), where r is the radius of the rotating object in meters.
To convert from RPM to meters per second, first convert RPM to radians per second by multiplying by 2π/60. Then, multiply by the radius of the rotating object to get the linear velocity in meters per second.
RPM and angular velocity are directly proportional. This means that as the RPM increases, the angular velocity also increases. This relationship can be expressed as: Angular velocity (radians per second) = RPM * (2π/60).
To convert from RPM to revolutions per second, simply divide the RPM by 60. This will give you the number of revolutions per second.
The most common units used for measuring RPM are revolutions per minute (RPM), revolutions per second (RPS), radians per second (rad/s), and degrees per second (deg/s). Other less common units include revolutions per hour, revolutions per day, and revolutions per week.
