(a)
Interpretation:
The following metric-English conversions are to be performed.
Concept introduction:
Metric system is a measurement system which has units of meter, liter and gram as the units for measuring length, volume and mass. Adoption of the metric system as a universal system of measurement has been resisted by several countries. In science, measurements are regularly recorded in metric units.

Answer to Problem 24E
The value of 800 m is equal to 875.27 yards.
Explanation of Solution
The value of 1 yard=0.914 m.
The conversion factor can be written as 1 yard0.914 m.
The conversion of 800 m into yard is given as,
800 m=1 yard0.914 m×800 m=875.27 yards
The value of 800 m is equal to 875.27 yards.

Answer to Problem 24E
The value of 0.375 kg is equal to 0.826 lb.
Explanation of Solution
The value of 1 kg=1000 g.
The conversion factor can be written as 1000 g1 kg.
The conversion of 0.375 kg into g is given as,
0.375 kg=1000 g1 kg×0.375 kg=375 g
The value of 1 lb=454 g.
The conversion factor can be written as 1 lb454 g.
The conversion of 375 g into lb is given as,
375 g=1 lb454 g×375 g=0.826 lb
The value of 0.375 kg is equal to 0.826 lb.

Answer to Problem 24E
The value of 1250 mL is equal to 0.3302 gallon.
Explanation of Solution
The value of 1 gallon=3785.41 mL.
The conversion factor can be written as 1 gallon3785.41 mL.
The conversion of 1250 mL into gallons is given as,
1250 mL=1 gallon3785.41 mL×1250 mL=0.3302 gallon.
The value of 1250 mL is equal to 0.3302 gallon.

Answer to Problem 24E
The value of 1.52×103 ds is equal to 2.533 min.
Explanation of Solution
The value of 1 s=10 ds.
The conversion factor can be written as 1 s10 ds.
The conversion of 1.52×103 ds into s is given as,
1.52×103 ds =1 s10 ds×1.52×103 ds =1.52×102 s.
The value of 1 min=60 s.
The conversion factor can be written as 1 min60 s.
The conversion of 1.52×102 s into min is given as,
1.52×102 s =1 min60 s×1.52×102 s=2.533 min.
The value of 1.52×103 ds is equal to 2.533 min.
