Question

When performing dimensional analysis, we usually use conversion factors. What is a conversion factor?

Answer 1

Answer:

A conversion factor is a variable that transforms the dimension of one variable into the terms of another variable.

Explanation:

Let be $x$ and $y$ two variables with diferent dimensions (units), $r$ is a conversion if transforms the dimension of one variable into the terms of the other variable. That is:

$y = r\cdot x$ (1)

Where:

$x$ - Input, [input unit]

$y$ - Output, [output unit]

$r$ - Conversion factor, [output unit] per [input unit]
