How to convert 646 yards to inches?

We know (by definition) that: $1 yd = 36 in$

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

\frac{1 yd}{646 yd} = \frac{36 in}{x in}

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

x in = \frac{646 yd}{1 yd} * 36 in \to x in = 23256 in

Conclusion: $646 yd = 23256 in$

Yards

The yard (abbreviation: yd) is an English unit of length, in both the British imperial and US customary systems of measurement, that comprises 3 feet or 36 inches. It is by international agreement in 1959 standardized as exactly 0.9144 meters.

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.
