This is a worksheet I created to help students practice converting within the metric system. There's an answer key provided. At the top of the paper, there are 7 blank spaces for the kids to fill in the letter: KHDUDCM ("U" stands for unit-grams, leters or meters). Our district teaches them the acronym: King Henry Doesn't Usually Drink Chocolate Milk to help them remember the metric steps. You can use it for practice, homework, a quiz or even a test.
