1. 5,468.9mm = 5.4689 m (see Table 1.1-1 p. 2)

2. 5.7 kl = 5,700,000 ml

3. 478.23 cg = 0.0047823 kg

4. 5.78 ng = 0.00000578 mg

5. 74.2 cm = 0.742 m

Section 1 - Length

Table 1: Microscope Slide
Length: 75 mm = 7.5 cm = 0.75 dm = 0.075 m
Width: 24 mm = 2.4 cm = 0.24 dm = 0.024 m

Table 2: Your Height
Height: 1810 mm = 181 cm = 18.1 dm = 1.81 m

1. Explain 2 advantages to using the metric system for measurement in scientific experiments.
   • Easy conversion by just moving the decimal point.
   • Consistent units among different countries and cultures.

2. Complete the following conversions.
   1. 745.98 ml = 0.74598 l.
   2. 5.87 kg = 5,870,000 mg.

3. For each unit below, indicate how many are in 1 meter.
   1. mm: 1,000 mm
   2. cm: 100 cm
   3. dm: 10 dm

4. If you were asked to measure each of the following, what metric unit would be the most appropriate to use?
   1. your mass: kg
   2. distance of a marathon race: km
   3. medical prescription in liquid form: ml
   4. medical prescription in solid form: mg

5. If you could buy either a pint or a liter bottle of pop for $1.25, which would you buy?

   Liter: p. 2 "a liter is slightly more than a quart", and a pint is half a quart, so a pint is less than 0.5 l. I get more pop in a liter for the same money, assuming I want more empty carbohydrates.
