Question 1:
Convert 12 centimeters (cm) into inches.
Solution:
From the table above we have: 1 cm = 0.393701 inches. Hence
12 cm = 12 * 0.393701 inches = 4.724412 inches
Question 2:
Convert 0.35 miles into centimeters (cm).
Solution:
The tables gives 1 mile = 160934.4 cm. Hence
0.35 miles = 0.35 * 160934.4 cm = 5.63270*104 cm
Question 3:
Convert 123.35 feet into kilometers (km).
Solution:
The tables gives 1 foot = 3.048*10-4 km. Hence
123.35 feet = 123.35 * 3.048*10-4 km = 0.0375970 km
Question 4:
Convert 11.56 inches into micrometers.
Solution:
The tables gives 1 inch = 25.4*103 micrometers. Hence
11.56 inches = 11.56 * 25.4*103 micrometers = 2.93624*105 micrometers
Question 5:
Convert 1238945.78 nanometers into yards.
Solution:
The tables gives 1 nanometer = 0.0010936*10-6 yards. Hence
1238945.78 nanometers = 1238945.78 * 0.0010936*10-6 yards = 0.00135491 yards
