Question

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

Answer 1

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

Step-by-step 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]
