Good, as it feels like a good habit to try a new language every once in a while and I didn't try PureScript yet I might give it a try. Conversion number between revolutions per minute rpm and revolutions per second rps is 0.016666666666667. This can lead to confusion when considering the units for frequency and the Planck constant.īut yeah, some things are the way they are, even though things could have been so much easier with decimal time, or even using base 12 as default instead of 10. There is controversy as to whether it is satisfactory in the SI to consider angles to be dimensionless. Thus a disc rotating at 60 revolutions per minute (rpm) is said to be rotating at either 2π rad/s or 1 Hz, where the former measures the angular velocity and the latter reflects the number of complete revolutions per second.Ĭonfusing stuff :) It does make sense to have angles be a dimension, but I guess the SI people have thought long about what would be the best choice.

On the Hertz Wikipedia page that is explained more clearly:Įven though angular velocity, angular frequency and the unit hertz all have the dimension 1/s, angular velocity and angular frequency are not expressed in hertz, but rather in an appropriate angular unit such as radians per second. How to convert Radian Per Second to Revolutions Per Minute (rad/s to rpm) 1 rad/s 9.5492965838197 rpm. So when 1 rpm = 1/60 Hz, then 1 Hz means one revolution per second (= 2π radians per second). How I understand that is that the Hz is the one that can be interpreted differently, not rpm. Acceleration - Angular Conversion Calculator 1 Radian/Square Second 9. One revolution per minute per second is equal to 0.1047197551143 rad/sec. If the non-SI unit rpm is considered a unit of frequency, then 1 rpm = 1/60 Hz Revolution/Minute Second : The revolution per minute per second is a unit of angular acceleration. It might be useful to include those units too.

If someone wants to make this change (and update the FAQ/documentation), I'd be okay with that.Īlso it makes sense to introduce the unit 'revolution(s)' or short 'rev', equal to 2π radians, so that you can define RPM as rev/min.Īctually in GNU units a revolution is defined as turn which is defined as circle which is defined as 2 pi radian. The fact that we are not compatible with units is actually a valid reason to change our default. So I guess it's time for me to reconsider my initial choice. I have added a FAQ entry ( ) regarding RPM some time ago, but this keeps on popping up. In insect, we chose the former ('RPM a unit of frequency'), while units apparently chose the latter ('unit of angular velocity'). If it instead is considered a unit of angular velocity and the word 'revolution' is considered to mean 2π radians, then 1 rpm = 2π/60 rad/s. If the non-SI unit rpm is considered a unit of frequency, then 1 rpm = 1/60 Hz. Wikipedia actually talks about those two conflicting definitions: Convert radian/second² rad/s² to revolution/minute/second r/ (min·s) 1 radian/second² rad/s² 9. Solution: Converting from radian per second to revolutions per minute is very easy. 1 radian per second, approximately 57.29578 degrees per second 1 radian per second, approximately 9.5493 revolutions per minute (rpm) 0.1047 radians per. Definition: In relation to the base unit of frequency > (hertz), 1 Radian Per Minute (rad/min) is equal to 0.002652582 hertz, while 1 Revolutions Per Minute (rpm) 0.01666666666 hertz. Always check the results rounding errors may occur. For example, 1 revolution per minute can be written as 1 RPM, 1 rev/min, or 1 r/min.But it should be scaled so that 1 RPM is 2π / min. 1 x 0.15915492006366 rpm 0.15915492006366 Revolutions Per Minute. Revolutions per minute can be abbreviated as RPM, and are also sometimes abbreviated as rev/min or r/min. Revolutions per minute are a measure of the number of turns, or revolutions, that occur per minute. Type in your own numbers in the form to convert the units Quick conversion chart of radians per second to RPM 1 radians per second to RPM 9. In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression. Radians per second can be abbreviated as rad/s for example, 1 radian per second can be written as 1 rad/s. Radians per second are a measure of angular frequency, or rotational speed, equal to the change in orientation or angle of an object in radians per second.
