Question

What must the value of a conversion factor always be?

Answer 1

One or unity or 1

Step-by-step explanation:

For example,

1 min =60 s

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

`1 = \frac{\text{60 s}}{\text{1 min}}`

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

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