How to convert 390 inches to meters?

We know (by definition) that: 1 in = 0.0254 m.

We can set up a proportion to solve for the number of meters.

1 in / 390 in = 0.0254 m / x m

Now, we cross multiply to solve for our unknown x:

x m = (390 in / 1 in) * 0.0254 m → x m = 9.905999999999999 m

Conclusion:

390 in = 9.905999999999999 m

Inches

The inch (abbreviation: in or ″) is a unit of length in the imperial and United States customary systems of measurement now formally equal to 1⁄36 yard but usually understood as 1⁄12 of a foot. Derived from the Roman uncia (twelfth), inch is also sometimes used to translate related units in other measurement systems, usually understood as deriving from the width of the human thumb. Traditional standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and defined as exactly 2.54 cm.

Meters

"The metre (international spelling) or meter (American spelling), (from the Greek noun μέτρον, \"measure\") is the base unit of length in the International System of Units (SI). The SI unit symbol is m. The metre is defined as the length of the path travelled by light in a vacuum in 1/299792458 seconds."
