Definition

quotient of change in width $Δ b$ (width is defined in ISO 80000-3: Space and time) and change in length $Δ l$ (length is defined in ISO 80000-3: Space and time) of an object:

$μ = \frac{Δ b}{Δ l}$

quotient de la variation de largeur $Δ b$ (la largeur est définie dans l'ISO 80000-3: Space and time) par la variation de longueur $Δ l$ (la longueur est définie dans l'ISO 80000-3: Space and time) d'un objet :

$μ = \frac{Δ b}{Δ l}$
