How to convert 100 decimeters to inches?

We know (by definition) that: $1 dm \approx 3.9370079 in$

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

\frac{1 dm}{100 dm} \approx \frac{3.9370079 in}{x in}

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

x in \approx \frac{100 dm}{1 dm} * 3.9370079 in \to x in \approx 393.70079 in

Conclusion: $100 dm \approx 393.70079 in$

100 decimeters is equivalent to 393.700787401575 inches

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.
