How many miles does 6710 steps with a long stride

It would depend on the length of your step, running, walking, jogging, up hill or down, over pavement or irregular terrain. If you measure it in feet and take and average then divide 5,280 by your measure to determine the relationship of your step to a mile.

That depends on your leg length/length of stride but as a rule of thumb a stride is reckoned to be approximately a yard as a rough average but people don't tend to stride out unless walking purposefully along an empty road but if they do you can reckon between 1700 and 1800 to the mile. For more normal walking/sauntering steps are shorter and there could be as many as 2500 to the mile...

Depends how tall you are and the length of your stride.

Yes, just just barely.
There are 1609.344 metres to a mile. Therefore a quarter mile is 1609.344 ÷ 4 = 402.336

If you are off for a walk, that is about 2 long strides.

To adjust your stride length on your Dashboard, please do the following:

1. Log into your Fitbit.com Dashboard.
2. Click on the gear icon in the upper right corner of your Dashboard and select "Settings."
3. You will see a field for Stride Length and Running Stride Length. ...
4. Click the "Update Profile" button to save your changes.

A lot of information on setup is available on your windows app or at this link:

That is an arbitrary question without an answer unless you provide some input as to what is the "accepted" length of a "step". Obviously, as people are of varying heights and thus varying leg length, the length of a step can vary widely. If you assume a step as the 30" pace that the US military associates with the march step, then you can calculate a distance.

16821 steps @ 30 inches per step = 504630 inches.

504630 inches divided by 12 = 42052.5 feet

Since the 5280 feet in one mile, then:

42052.5 feet divided by 5280 = 7.9644886363636... miles.

go to google and type in 140s accusplit eagle and you will get a lot of answers. It would take me forever to type it here and as you are obviously able to use a compute,r the solution I suggest will be your best bet :-)

you want to use the 5w20 for best fuel efficiency and easier cold starts especially in bc. multiweight oil has made great strides in the years past. also synthetic oil is a good alternative but you should also use the manufacturer's recommended viscosity. the thinner oil also allows better lubrication on smaller passageways.
