Question

What is a conversion factor?

Answer 1

A conversion factor is a factor that is used to change between units, and therefore gives the relationship between two units.

Explanation:

For example, a common conversion factor would be

`1 \ "km" = 1000 \ "m"`

or

`1 \ "minute" = 60 \ "seconds"`

So, when we want to convert between two certain units, we can find their conversion factor (like `1,12,60,...`) and then we will find their relationship.

Here is a detailed picture that shows most conversion factors:
