While the unit most compatible with the SI (in the sense of simplifying mathematical formulae) would be radians per second, not only the U.S. but other parts of the world commonly use revolutions per minute.

What is the si unit for average velocity?
The SI unit for velocity (average, starting, final,usual, extraordinary, lowest. highest, but NOT angular) is metres per second.
Define angular velocityWhat is its SI unit?
Angular velocity is a measurement of how fast something is turning. Everyone has heard of "RPM", which stands for "Revolutions Per Minute" ... how many complete turns an object makes in one minute. That's a perfectly good measurement of angular velocity, although in Physics, angular velocity is normally given in different units. The standard unit for angular velocity is "radians per second". Each complete turn covers (2 pi) radians (same as 360 degrees). And there are 60 seconds in one minute. So if you know the RPM, you can multiply RPM by (2 pi / 60) = 0.10472 to get angular velocity in standard units. An old LP phonograph record (remember those ?) playing at 33-1/3 RPM has an angular velocity of about 3.5 radians per second. A car engine idling at 1,000 RPM is turning at about 104.7 radians per second.
What quantities are needed to calculate angular momentum?
"Rate of change" means that you divide something by time ("per unit time" or "per second"), so you would use the units of angular momentum, divided by seconds.I am not aware of any special name for this concept.
What unit belongs to the u.s and the metric systems?
The unit that belongs to both the U.S. customary system and the metric system is the liter (for volume), the meter (for length), and the gram (for mass).
Is foot customary or metric?
It is a customary unit.
Is a second customary or metric?
It is the basic unit of time in both systems.
Define constant angular velocity and explain how it is applies to a CD?
Angular velocity is the measure of angular displacement (in one or the opposite) direction over a unit period of time. In the context of CDs , one unit in which this can be measured is the number of revolutions per second. A constant angular velocity means that the CD is turning through the same angle each second.
How is angular velocity related to tangential velocity?
The time, T , it takes for an object to go thru one comblete rotation of 360 degrees or 2pi radians is its "period." The rate at which it completes the rotation is its "angular velocity." The rate is the angle (in radians) divided by the time. So , Angular Velocity = 2 pi / T.
What is the si unit for average velocity?
The SI unit for velocity (average, starting, final,usual, extraordinary, lowest. highest, but NOT angular) is metres per second.
What is the conversion value of 10.000 g in rpm?
a mass/weight unit cannot be converted into rpm, because rpm is unit of angular velocity.
What is the dimension of angular velocity?
The dimension of angular velocity is reciprocal time . . . 1/time or T-1 . It'll be stated as "some angle" per "unit of time", like "45 revolutions per minute", and angles are dimensionless.
What is the meaning of angular frequency for a body undergoing simple harmonic motion?
Angular frequency differs from frequency by factor '2Pie'. It has the dimension of reciprocal time(same as angular speed). Its unit is radian/sec. Or you can simply say that angular frequency is the magnitude of angular velocity(a vector quantity).

Is Fahrenheit a customary unit or metric unit?
Fahrenheit is a customary unit
Is feet in the customary unit or the metric unit?
customary
Is a liter a US Customary unit?
it is in the us customary unit or else we wouldnt be learning about. there for it is in the us customary unit.
How do you define constant angular velocity?
Assuming you mean "Constant angular velocity", let's break it down. Constant, meaning "something that does not or cannot change or vary". Velocity is distance over time, or "speed". Angular velocity is the angular distance (such as "one rotation") An example of velocity would be 60 Miles per Hour (MPH). That would be that in one hour, an object would travel 60 miles. An example of angular velocity would be 45 Degrees per Hour. For a real world example, Earth turns 1 full revolution every day. "1 revolution per day" is an angular velocity. Lets convert this to a different unit. There are 360 degrees in 1 revolution. Therefor, we can say that Earth has an angular velocity of 360 degrees per day." We can convert this unit again. There are 24 hours in one day. 360 divided by 24 = 15 degrees per hour, which is another example of angular velocity. Simply put, angular velocity is the speed at which something is rotating. In computers, angular velocity is commonly used to describe a mechanical hard disk drive. Hard drive speeds are measured in Rotations per Minute (RPM) and are commonly 4200, 5200 or 7200 RPM. The faster the speed of the hard drive, the faster it can read and write data.
