The Metric System

As you recall, to convert from 500 grams (basic unit) to kilograms, move the decimal three places to the left, which is 0.500 or 0.5 kg. 225,000 x 180 x 0.5 kilograms = 20,250,000 kg. Now, to convert to tons, you must first change kilograms to pounds. Since 1 kg = 2.2046 lb, multiply 2.2046 x 20,250,000 = 44,643,150 lb. ................
