Some countries measure temperature in Fahrenheit (F), while other countries use Celsius (C). Similarly, for distance, some use miles and others use kilometers. As a frequent traveler, you may be in need of a quick approximate conversion scheme that you can do in your head.

a. Fahrenheit and Celsius are related by the equation F = 32+(9/5)C.Verify the following simple conversion scheme for going from Celsius to Fahrenheit: A rough approximation is to double the Celsius temperature and add 32. To refine your approximation, shift the decimal place to the left in the doubled number (2C) and subtract it from the approximation obtained previously:

b. Determine a simple scheme to convert from Fahrenheit to Celsius.

c. Determine a simple scheme to convert from miles to kilometers.

d. Determine a simple scheme to convert from kilometers to miles.
