Information from Wikipedia Metric prefix:

A metric prefix or SI prefix is a unit prefix that precedes a basic unit of measure to indicate a decadic multiple or fraction of the unit. Each prefix has a unique symbol that is prepended to the unit symbol. The prefix kilo-, for example, may be added to gram to indicate multiplication by one thousand; one kilogram is equal to one thousand grams. The prefix centi-, likewise, may be added to metre to indicate division by one hundred; one centimetre is equal to one hundredth of a metre.

Weight: measured in grams, 1kg is one kilogram = 1000 grams ~ approximately 2lb or 3.3oz

Length / distance: measured in meters, 1km is one kilometer = 1000 meters ~ approximately 1093yd

Volume: measured in liters, 1l is one liter = 1000 mililiter or 1000ml ~ approximately 2.1134US pt lqd.

    I looked this up as I was helping a student with this topic to see if there were any alternatives to the one I use. I am glad to see that there are, but I still feel that the one I use (invented by a year 7 pupil of mine) works better than all of these: “Killer Hedgehogs Drive (motorbikes/lorries/go-karts/jeeps) down crowded motorways”. The choice of vehicle clearly defines the base required.
