If you remember the saying King Henry Doesn't Usually Drink Chocolate Milk, converting is EASY!!!!!!!!! K = kilo, H = hecto, D = deka, U = the unit you are using ( liter, meter, gram) D = deci, C= centi, and M = milli. Then you move the decimal point whichever way you go, how many places you move. 50 dm = 5 meters
