How many rad/h in 21 r/d? The answer is 5.49773931 rad/h, so 21 r/d is equal to 5.49773931 rad/h. Let’s discuss it in detail!
First of all, we must know that r/d and rad/h are units of angular velocity, r/d is the abbreviation of Revolution Per Day, rad/h is the abbreviation of Radian Per Hour.
Then, we want to convert 21 r/d into rad/h, we should get the conversion formula of r/d to rad/h first.
Fortunately, through the Revolution Per Day to Radian Per Hour converter page, we can easily get the r/d to rad/h conversion formula: 1 r/d = 0.26179711 rad/h. The number 0.26179711 is called the conversion factor of r/d to rad/h.
So, convert r/d to rad/h, just multiply r/d by the conversion factor 0.26179711.
1 r/d = 0.26179711 rad/h
21 r/d = 21 * 0.26179711 rad/h = 5.49773931 rad/h
The result is out: 21 r/d = 5.49773931 rad/h.
Is not it simple?
If you still don’t understand, take it easy, we can give another example:
1 r/d = 0.26179711 rad/h
562 r/d = 562 * 0.26179711 rad/h = 147.12997582 rad/h
Thus, 562 r/d = 147.12997582 rad/h.
Well, through the above detailed explanation, you should have mastered the technique of how to convert r/d to rad/h. If you still can’t, don’t worry, just use the r/d to rad/h conversion tool we provide above, enter the conversion value you want, our calculator tool will give the result immediately, and the maximum accuracy of result can be retained to 10 digits, which is very convenient and fast. Looking forward to your use.
OK, at this point, we already know that 21 r/d is equal to 5.49773931 rad/h. The following questions can be easily solved by this conversion:
