Metric Measurement

  1. 1. Measurement<br />Dr Schroeder 2.18.10<br />
  2. 2. SI Units<br />Length: meter<br />Mass: kilogram<br />Time: seconds, hours, days<br />Temperature: celsius<br />Volume: liter<br />
  3. 3. SI Unit Prefixes<br />
  4. 4. Conversions with units<br />1 kilometer = 1,000 meters<br />1 hectometer = 100 meters<br />1 dekameter = 10 meters<br />10 decimeters = 1 meter<br />100 centimeters = 1 meter<br />1,000 millimeters = 1 meter<br />1,000,000 micrometers = 1 meter<br />All are the same for grams and liters<br />
  5. 5. Conversions between Units<br />If you need to convert between units, you use the scale/equivalence ratio to set up a proportion.<br />Example: 8 meters = ____ centimeters<br />Solve by cross multiplication.<br />
  6. 6. Another Example<br />150 meters = ___ hectometers <br />The scale is 1 hectometer = 100 meters. <br />Set up the proportion:<br />Cross-multiply and solve<br />Make sure the units are in corresponding positions<br />
  7. 7. Another Example<br />27 kilometers = ______ centimeters<br />You cannot directly convert kilometers to centimeters. <br />You need to convert kilometers to meters and then convert meters to centimeters. <br />Cross-multiply and solve<br />Make sure the units are in corresponding positions<br />
  8. 8. Another Example<br />Cross-multiply and solve<br />Make sure the units are in corresponding positions<br />
  9. 9. More Conversions<br />9 hectometers = ____ meters<br />575 milligrams= ____ grams<br />62 liters= ____ deciliters<br />35 kilometers = ____ meters<br />3 grams = ____ micrograms<br />58 hectograms = ___ milligrams<br />1800 centimeters = ____ dekameters<br />59 hectoliters= ____ centiliters<br />
