Have you ever been confused by FOOT and FEET… when to use each?
FOOT has two plurals.
The usual one is FEET; the other one is FOOT.
The most common use of the plural FOOT is as a unit of measure.
It is joined to a number with a hyphen.
>We used a four-FOOT step ladder to climb onto the low roof for the best shot.
>It was an eight-FOOT drop to the ground.
When you combine “foot” with numbers greater than “one” to talk about DISTANCE, use “feet”:
>The live unit is now only 6 FEET away.
Use “feet” between a number and an adjective.
>The suspect is six FEET nine inches tall.
(“Tall” is a predicate adjective modifying “suspect.”)
Use “foot” when you use a number on each side of it.
>The suspect is six FOOT nine.
Mrs. B is five FEET six inches tall.
If she were five FOOT ten, she would be happier with her weight.
