How many metres are in a mile?
One mile is 1609.344 metres. To convert any amount, multiply by 1609.344. Going the other way, one metre is 0.000621371192 miles.
What is the formula to convert mi to m?
Multiply the mile figure by 1609.344. So m = mi × 1609.344. For a quick mental estimate, multiplying by about 1609 gets you within a percent or so, which is close enough for most everyday purposes.
What does a mile actually look like?
One mile is a comfortable 20-minute walk. The statute mile is exactly 1,609.344 metres, a consequence of the inch being fixed at 25.4 mm in 1959. It remains the road unit in the US and UK.
And what is a metre?
One metre is roughly the height of a kitchen counter plus a bit. The metre has been defined since 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second — a definition that ties it to a physical constant rather than to any object.
Is this conversion exact?
Yes. Since the 1959 international yard and pound agreement, the imperial and metric systems are related by exact definitions rather than measurements — the inch is exactly 25.4 mm and the pound exactly 0.45359237 kg. Everything derived from those, including this conversion, is therefore exact. Round at the end rather than partway through, since rounding mi before converting introduces an error the conversion then multiplies.

Getting it right
This conversion is exact by definition, so the only limit on accuracy is how many digits you keep. Round at the end rather than partway through — rounding mi to a whole number before converting introduces an error that the conversion then multiplies.
