Engine hours vs. miles: How does this calculation differ from the mileage?
The mileage represents the distance the car has traveled. Meanwhile, our calculations refer to the runtime of the engine. Although idling does not change the mileage, it does affect the engine's condition as it continues to run.
What is the average engine hours for 200k miles?
The average engine hours for 200,000 miles is approximately 6,700 engine hours, assuming your average speed was 30 mph. To find it:
 Determine your average speed, for example, 30 mph.
 Divide 200,000 miles by 30 mph to get 6,667 engine hours.
 Optionally, round the result to 6,700 engine hours.
What is the average engine hours for 50,000 miles?
If your average speed was 30 mph, then your engine hours equals approximately 1,700 for 50,000 miles. You can calculate it in the following way:
 Write down your average speed; in this case, 30 mph.
 Divide 50,000 miles by 30 mph.
 The result of 1,667 is the value of average engine hours.
 This value can be further rounded up to 1,700 engine hours.
How do I convert idle hours to mile?
To determine the idle hours to miles conversion, you need to:

Estimate your engine idle hours from your onboard computer.

Determine the equivalent miles per hour of engine running, which is usually 30 mph.

Multiply both values to get the equivalent distance in miles.

These steps can be written in the following formula:
distance = engine hours × miles per hour of running
