Post-Lab: Metrics Lab

Complete these questions after you complete the review of the metric system lab.

Activity 1: Metrics Units for Length

• Place the following units in DECREASING size: micrometer, centimeter, kilometer, meter, millimeter.

• You wish to convert a small measurement, such as a millimeter, into a bigger measurement, meters. Will the resulting number (meters) be bigger or smaller than the number in millimeters?

• State how many meters are in the following units listed below:
  • a. 1 m = ________________ km
  • b. 1 m = ________________ µm
  • c. 1 m = ________________ mm
  • d. 1 m = ________________ dm
  • e. 1 m = ________________ cm

• Convert the following measurements:
  • a. 2.21 cm = ________________mm
  • b. 108 cm = ________________mm
  • c. 1,010 µm = ________________mm
  • d. 5.87 mm = ________________µm
  • e. 36.2 dm = ________________m
  • f. 0.000005 km = ________________µm
