I recently bought a computer to monitor rpm.

This is more like a physics question or maybe I don't know this part in my project. The problem is that I'm getting wrong readings with the below logic. Please refer to the attached diagram and excerpt from my sketch and suggest me if I'm making any physics calculative mistakes. Posting it inline as you have done makes it much harder to read or copy and paste for diagnosis. It's still not too late to edit your post and do this. You'll make potential helpers much happier. Why do you manually convert from circumference to radius, then have the program convert back to circumference in the calculations.

Enter a value to the speed field above, in order to see the results in this table. Cancel Print. Number of digits: 10 x notation for big numbers:. Minas E. Lemonis, PhD - Updated: March 27,

You can also use it as an RPM to mph calculator. The first section explains the RPM definition and its extensive use in the automotive industry. In the second part, you will see how engine RPM relates to vehicle speed, and understand the effects of drivetrain transmission and tire size. Finally, we will show you, with an example, how to use our RPM calculator. We've also probably noticed that engine noise goes up with RPM. But what exactly is RPM? Why is it so extensively used when we talk about cars and engines? The RPM term can be employed for any rotating object.

And each complete revolution will cover the same distance - the circumference of the wheel. Find More Posts by a1penguin. Like Oldsteve asked, how far are your measurments of?

Speed is the rate of change in position of an object, regardless of direction of travel.

It's normal for his engine. Helmet Clan. That's because you're measuring whole revolutions and you're only measuring for one second. It seem too small. The count is by nature, an integer. If you must, cli and sei might be better, but I don't think you need to. OldSteve January 13, , pm 2. Everywhere Threads This forum This thread. Trackbacks are Off. P Wonky Donkey. Senior Member. Diesel engines have lower rpm's, so they can't be compared to petrols Hi Oldsteve, Directly or indirectly using the radius from the circumference yeilds the same results, however the question I have is whether measuring at different points on the wheel will produce different readings or same?
