Is the Jacobian Equal to the Quotient of Scale Factors?

[Jhenrique]

In somewhere in wikipedia, I found a "shortcut" for compute the jacobian, the formula is: \frac{\partial(q_1 , q_2 , q_3)}{\partial (x, y, z)} = h_1 h_2 h_3 where q represents the coordinate of other system and h its factor of scale.

I know that this relationship is true. What I'd like of know is if this equation below is true: \frac{\partial(q_1 , q_2 , q_3)}{\partial (Q_1, Q_2, Q_3)} = \frac{h_1 h_2 h_3}{H_1 H_2 H_3} where Q represents the coordinate of another system and H its factor of scale.

Is correct to affirm that the jacobian is equal to the quotient between the scale factors?

What you did is to invent a definition of \frac{\partial(q_1 , q_2 , q_3)}{\partial (Q_1, Q_2, Q_3)} . It is not true nor false: it is a definition.
