What is Unit Conversion?

A unit conversion is the expression of the same feature in a different unit of measurement. Time, for example, can be stated in minutes rather than hours, and distance can be translated from miles to kilometres, feet, or any other length measurement.

We know,

There are 12 inches in 1 foot

There are 3 feet in 1 yard

Now, to convert feet to inches

= 180 /12

Then, feet to yards

= 180 /12 x 13

= 60 / 12

= 5 yard

Thus, Ellen need to 5 yard of ribbon.
