Metric Lab 1

For this short lab, you are asked to use your knowledge of the metric system to help you answer the following questions. Show your work on this page.

1. Convert each of the following measurements into an equivalent measurement that makes more sense to you than the one given. After converting the odd units to something that makes more sense, identify something that is about that size.

  1. 30,000,000,000 pm = ______
  1. 23,000,000,000,000 pg = ______
  1. 0.00000000023 Gm = ______
  1. 0.0000000035 Mg = ______

2. Without using a meter stick or a balance, try to find something in the room that has the same size as measurements listed above. Write that item on the first blank below. After estimating all four measurements, measure them with a meter stick or a balance and record that measurement in the second blank.

Item that you think is right size Measured size of that item

a. ______

b. ______

c. ______

d. ______

3. Using the percent error equation, calculate your percent error for each of the above measurements. Record those measurements in the blanks. Show work

  1. ______b. ______
  1. ______d. ______

4. For the following awkward measurements, convert to something more easily understood and then give an example of something that might be that size.

Which is about:
