This Book is a Ruler

This is a book you’d give to a bibliophile who needs a ruler or a builder who likes to read. The book itself is a 6-inch ruler that is half an inch thick with tick marks down the sides. It’s a helpful tool by itself, but we made it even handier by adding some measurement conversions. However, a book full of conversion tables is beyond boring, so we added some fun measurement facts, trivia and dad jokes.
