You should memorize these facts and know how to use the conversions! Converting Units Metric: Kilo means 1000 so 1 kg = 1000 grams Centi means 1/100th, so 100 cm = 1 m Milli means 1/1000th, 1000 mm = 1 m Standard system: 1 foot = 12 inches 1 yard = 3 feet 1 mile = 5280 feet 1 cup = 8 ounces 1 pint = 2 cups 1 quart = 2 pints 1 gallon = 4 quarts 1 pound = 16 ounces 1 ton = 2000 pound You should memorize these facts and know how to use the conversions!
