Since the adoption of the international yard on 1 July 1959,
inch is based on the metric system and **one inch is defined as exactly 2.54 cm**.
It becomes trivial to deduce the following formula:

$$ l_{ (cm) } = 2.54 \times l_{ (in) } $$

and *vice-versa*:

$$ l_{ (in) } = \frac { l_{ (cm) } } {2.54} $$
