Meters to Inches formula
The factor from meters to inches is 39.3700787.
in = m × 39.3700787
Why this factor: the meter and the inch are both defined against the meter, so dividing one definition by the other gives 39.3700787 directly. Both definitions are set out in full below.
To go the other way, divide by 39.3700787 — or use the Inches to Meters converter, which is the same calculation reversed.
Worked example

What is a meter?
The meter is the SI base unit of length — the reference every other length unit is now defined against.
Definition: Since 1983 the meter has been defined by fixing the speed of light in vacuum at exactly 299,792,458 meters per second, so a meter is the distance light travels in 1/299,792,458 of a second.
Where it is used: Universal in science, engineering and everyday measurement everywhere except the United States.
What is an inch?
An inch is one twelfth of a foot, used for small dimensions and for screen and wheel sizes globally.
Definition: Exactly 25.4 millimeters since the 1959 International Yard and Pound Agreement — an exact, not approximate, relation.
Where it is used: Screen diagonals, pipe and fastener sizes, tire and wheel diameters, and print layout worldwide.
Meters vs Inches
The meter is an SI unit while the inch is an imperial unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
