Converting Metric MeasurementsDate: 05/26/98 at 20:28:00 From: Charles Lozada Subject: Converting metric measurements How many kilometers are in a meter? How many kilometers are in a centimeter? How many meters are in a centimeter? How many kilometers are in a decimeter? How many meters are in a hectometer? How many centimeters are in a millimeter? How many centimeters are in a kilometers? Date: 06/01/98 at 12:14:06 From: Doctor Mateo Subject: Re: Converting metric measurements Hello Charles, The metric system uses base 10 so conversions within the metric system result in moving the decimal point forward or backward: kilo - means 1000 hecto - means 100 deka - means 10 deci - means 1/10 centi - means 1/100 milli - means 1/1000 Sometimes the conversion facts are illustrated with metric stair steps: kilo ________ ) hecto- )________ ) deka- )________ )metric base (meter, liter, gram) )___________ ) deci- )_________ ) centi- )_________ ) milli- )_______ Each time you move down a step you will move the decimal point forward one place. Each time you climb up a step you move the decimal point backward one step. Consider some of the following: 1 m = .001 km (you climb up three steps) 12 cm = .00012 km (you climb up five steps) 81 cm = .81 m (you climb up two steps) 3 dm = .0003 km (you climb up four steps) 1 hm = 100 m (you go down two steps) 7 mm = .7 cm (you climb up one step) 1.2 km = 120,000 cm (you go down five steps) Make good use of the conversion facts. They are useful in math, science, industry, and all kinds of places. -Doctor Mateo, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
