Which of the following is not a unit of length? Circle your answer. Is it yards, inches, millimetres, or degrees?
There are many common metric and imperial units of length. The metric units of length include kilometres or kilometres, metres, centimetres, and millimetres. Imperial units of length include miles, yards, feet, and inches. Three of our four options are listed here, millimetres, yards, and inches. This means that all three of these are units of length. Therefore, they are not the correct answer.
The only option remaining is degrees. And we know that degrees is a unit that measures angles. We can therefore say that, out of the four options, yards, inches, millimetres, and degrees, the one that is not a unit of length is degrees.
