Meters to Miles
Convert meters (m) to miles (mi). Both measure distance and dimension, and the conversion comes up in construction, navigation, sports work.
The Formula
``
miles = meters × 0.000621371192237
meters = miles × 1609.344
`
One meter is 6.2137e-4 miles, and one mile is 1,609.34 meters.

What Each Unit Is
Meters (m) — the distance light travels in a vacuum in 1/299,792,458 of a second — the SI base unit of length. Defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, then by a platinum bar, and since 1983 by the speed of light.
Miles (mi) — exactly 1,609.344 metres, by the 1959 international yard and pound agreement. The Roman mille passus — a thousand paces — later fixed by English statute at 5,280 feet.
A Sense of Scale
A doorway is about 2 m tall- An Olympic pool is 50 m
- A city block is 80–120 m
- A brisk walk covers a mile in 15 minutes
- A marathon is 26.2 miles
- US speed limits are in mph
Precision
The factor 0.000621371192237 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 m with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 m becomes | Error |
|---|---|---|---|
| 0 | 0 | 0 | 100.0000% |
| 1 | 0 | 0 | 100.0000% |
| 2 | 0 | 0 | 100.0000% |
| 3 | 0.001 | 0.137 | 60.9344% |
| 4 | 0.0006 | 0.0822 | 3.4394% |
The right number of significant figures is set by your input, not by the converter. If you measured meters to three significant figures, the answer in miles is only good to three — writing more digits claims precision the measurement never had.
