So, it takes about 6.3 radians to equal one full 360-degree revolution of the car tire. In terms of angles, one revolution per minute equals 360 degrees of rotation per minute. Simply multiply your rad/s by the conversion factor above to get your rpm equivalent. In relation to the base unit of => (hertz), 1 Radian Per Second (rad/s) is equal to 0.159154943 hertz, while 1 Revolutions Per Minute (rpm) = 0.01666666666 hertz. ![]() How to convert Radian Per Second to Revolutions Per Minute (rad/s to rpm)?ġ x 9.5492965838197 rpm = 9.5492965838197 Revolutions Per Minute.Īlways check the results rounding errors may occur. ![]() The base unit for frequency is hertz (Non-SI/Derived Unit) How to convert Radian Per Second to Revolutions Per Minute (rad/s to rpm) 1 rad/s 9.5492965838197 rpm. 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: Radian Per Second to Revolutions Per Minute You can also get the formula used in Rad to Rem conversion along with a table representing the entire conversion. If you encounter any issues to convert, this tool is the answer that gives you the exact conversion of units. 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. Converting Rad to Rem is easy, for you only have to select the units first and the value you want to convert. 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. You can extend the formula that convert angle to distance : (3) L r. If the previous demonstration did not convince you. The conversion can be done thanks to the following formula: (1) v r. So when 1 rpm = 1/60 Hz, then 1 Hz means one revolution per second (= 2π radians per second). It implies that the speed of the object is also equal to r ×. How I understand that is that the Hz is the one that can be interpreted differently, not rpm. rpm to rad/s conversion table: 0.1 rpm 0.01047 rad/s, 2.1 rpm 0.2199 rad/s, 4.1 rpm 0.4294 rad/s, 7 rpm 0.733 rad/s 0.2 rpm 0.02094 rad/s, 2. If the non-SI unit rpm is considered a unit of frequency, then 1 rpm = 1/60 Hz 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. For example, 2rad/s multiplied by is equal to rpm. 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"). Put the Rad/s Value in (Rad/s) below / 60 x (Rad/s) 2 RPM OR 60 x (Rad/s) 6.28318 RPM Note: 3.14159 2 (2 x 3.14159) 6.28318 Quora User Future IITian 2 y Radians Per sec × 60 Radian per min 1 rev. 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. Rad/s is given and you want to convert it into Revolutions per minute. 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: But it should be scaled so that 1 RPM is 2π / min.
