Question

What must the value of a conversion factor always be?

Answer 1

Answer:

One or unity or 1

Explanation:

For example,  

1 min =60 s

If we divide each side of the equation by 1 min, we get

$1 = \dfrac{\text{60 s}}{\text{1 min}}$

If we divide each side of the equation by 60 s, we get

$\dfrac{\text{1 min}}{\text{60 s}} = 1\\\\\text{Thus, both conversion factors, \dfrac{\text{60 s}}{\text{1 min}} and \dfrac{\text{1 min}}{\text{60 s}} , equal 1.}$
