Exercise:

1. Convert the following

3 m = 300 cm

83 m = 83,000,000 µm

41,692 m = 41,692,000 mm

110 kilometers = 110,000 m = 110,000,000 mm

3.7 hectometers = 370 m = 37,000 cm

451,000,000 µm = 451 m = 45.1 dam

2. Imagine a field is about 100 meters long. If you run a 5K race how many meters is it? Approx. how many “fields” does this equate to?

-5000 meters

-50 fields

3. Measure the following objects

A) Your computer screen (in meters):

Length: 0.31 meters

Width: 0.52 meters

Area: 0.1612 meters^2

Volume: 0.004836 meters^3

B) A 100mL beaker (in millimeters):

Length: 250 millimeters

Width: 30 millimeters

Area: 7,500 millimeters^2

Volume: 225,000 millimeters^3

C) Your lab kit box lid (in centimeters):

Length: 40 centimeters

Width: 35 centimeters

Area: 1,400 centimeters^2

Volume: 11,200 centimeters^3

4. Determine the mass of the objects listed below (in grams). Pay attention to the units. Since you do not have a metric scale, we will provide you data to work with.

A) Baseball:

Mass (measurement 1): .145 kg

Mass (measurement 2): 145.05 g

Mass (measurement 3): 145,750.77 mg

Mass (average): 145.26692 g

Convert: 0.14527 kg

B) Piece of fruit:

Mass (measurement 1): 310 g

Mass (measurement 2): 0.318 kg

Mass (measurement 3): 309,143 mg

Mass (average): 31,238.1 cg

Convert: 312.381 g

5. Determine the...
