7-31.

Felipe knew that he was $60$ inches tall and that his sister Maria was $5$ feet tall.

Felipe said, "Hey, I'm $\it12$ times as tall as you, since $\it5$ times $\it12$ equals $\it60$." At first, Maria was puzzled, but then she said, "That's not true, and I know why."

Explain in a complete sentence what Maria realized.

Inches and feet are different measuring units.
One foot is $12$ inches.
