Move the decimal point to the right of a metric number to see how many are in a larger metric unit. For example, the term kilo always means "thousand" in metric. So by moving the decimal point over three places to the right, you'll see how many meters are in a kilometer, which is 1000. This is the same for grams and kilograms. The decimal would move to the left three places if you are converting a smaller unit into a larger unit. A liter is .001 of a kiloliter. Hecto means 100, or two decimal places when converting, while deca means 10. Deci is .01, centi is .001 and milli is .001 of the base unit.
Multiply the number of meters by 3.28 in order to covert to feet.
Multiply the number of grams by .0022 to covert to pounds.
Multiply the number of liters by 1.05 to convert to quarts.
