This means you can’t use abstract measurements. No more six-foot-tall men. Instead you must describe a man’s size based on how your character or narrator perceives a man whose height is seventy-two inches. A character might say “a man too tall to kiss” or “a man her dad’s size when he’s kneeling in church.” You may not describe the temperature as being one hundred degrees. Or trips as being fifty miles long. All standardized measurements preclude you describing how your character sees the world.
