The rpm of the engine - revolutions per minute
Max RPM is the term for maximum revolutions per minute of a car engine. Red line is another term for max rpm.
it would depend on the speed of the car or the diameter of the tire.
Revolutions per minute of the crankshaft in the engine.
no, tacho only indiacte the revolutions per minute of the engine when running
If you mean in context of motor sports then its revolutions. When a car reaches 3000 Revs it means the motor is turning at 3000 revolutions per minute
you cant that's 2 different things Depending on the size of the tire... revolutions in a car RPM are talking about the engines crank shaft RPM... now if you want to measure that in Speed... you will need to do the convertion to the size of the tire since MILE is a distance and Revolution is a spin... If you want to measure the size of the crankshaft... well easy... take out the shaft from your car and start rotating it in a street until you reach 10000... that is the distance... as per the time.. do the math 10000 in one minute... there will be a lot of 0 in your result.
It is a tachometer, an instrument showing the speed of the engine in RPM (revolutions per minute).
The speed of an car per hour[s] is the speed that the car is going.Example- If a car is going 75 miles for5 hours,what is the cars speed.The car speed is 75 miles per hour.
That would depend upon the size of the tire. My car has tires that are about 221/4" in diameter which means they have circumference: circumference = π x diameter ≈69.9" which is the distance travelled in one complete revolution of the tire. 1 mile = 63360 in ⇒ revolutions = 1 mile ÷ circumference_of_tire ≈ 63360 in ÷ 69.9 in ≈ 906.43 revolutions per mile My bicycle has tires that are about 271/2" in diameter meaning the number of revolutions is: revolutions ≈ 63360 in ÷ (π x 271/2 in) ≈ 733.39 revolutions per mile
You would need to know something about the size of the tire (its radius, circumfrence, etc.) Knowing this, you can convert revolutions per minute into some form of distance (using the knowledge that 1 revolution = circumference of the tire). The distance can then be converted to kilometers if it is not already. You would also need to convert minutes into hours (knowing that 60 minutes = 1 hour). This should give your speed in kph (kilometers per hour).
RPM (Revolutions Per Minute), generally associated with the rotation of the crankshaft in a vehicle.
