 DECIMALS in MEASUREMENT Prefixes for units of length, volume, and mass in the metric system: Prefix Multiply by milli- 0.001 (1/1000) centi- 0.01 (1/100) deci- 0.1 (1/10) deka- 10 hecto- 100 kilo- 1000
 LENGTH The standard unit of lengthin the metric system is the meter. 1 millimeter = 0.001 meter 1 centimeter = 0.01 meter 1 decimeter = 0.1 meter 1 kilometer = 1000 meters Abbreviations 1 millimeter = 1 mm 1 centimeter = 1 cm 1 meter = 1 m 1 decimeter = 1 dm 1 kilometer = 1 km Length Conversion Calculator FOR REFERENCE: One meter is about half the height of a very tall adult. A centimeter is a little less than the diameter of a dime A millimeter is about the thickness of a dime.
 MASS The standard unit of massin the metric system is the gram. 1 milligram = 0.001 gram 1 centigram = 0.01 gram 1 decigram = 0.1 gram 1 kilogram = 1000 grams Abbreviations 1 milligram = 1 mg 1 centigram = 1 cg 1 decigram = 1 dg 1 gram = 1 g 1 kilogram = 1 kg Mass Conversion Calculator FOR REFERENCE: A gram is about the mass of a paper clip.One kilogram is about the mass of a liter of water.
 VOLUME The standard unit of volumein the metric system is the liter. 1 milliliter = 0.001 liter 1 centiliter = 0.01 liter 1 deciliter = 0.1 liter 1 kiloliter = 1000 liters Abbreviations 1 milliliter = 1 ml 1 centiliter = 1 cl 1 deciliter = 1 dl 1 liter = 1 l 1 kiloliter = 1 kl FOR REFERENCE: One liter = 1000 cubic centimeters in volume. One liter is slightly more than a quart. One teaspoon equals about 5 milliliters.
 TIME Time conversions: 1 minute = 60 seconds 1 hour = 60 minutes = 3600 seconds 1 day = 24 hours 1 week = 7 days 1 year = 365 1/4 days (for the Earth to travel once around the sun) Calendar Calculator FOR REFERENCE: Every three calendar years will have 365 days. The fourth year is a "leap year" of 366 days (this makes up for the extra quarter day over four years). 1992, 1996, 2000, and 2004 are leap years.
 TEMPERATURE Celsius Fahrenheit Kelvin 100 212 373 Boiling point of water 30 86 303 A hot day 20 68 293 Average room temperature 0 32 273 Water melting/freezing point -40 -40 233 F and C are the same. -90 -130 183 Lowest recorded * Converstion Tables & Calculator FOR REFERENCE: Degrees Celsius are used in the metric system. The boiling point of water (at sea level) is 100°C. The freezing point of water (at sea level) is 0°C. * -89°C / -129°F ( Vostok, Antarctica, July 1983 )
