Question

USING PYTHON 2

The United States uses the English system of (length) measurements. The rest of the world uses the metric system. So, people who travel abroad and companies that trade with foreign partners often need to convert English measurements to metric ones and vice versa.

Here is a table that shows the six major units of length measurements of the English system:

English 1 inch = 2.54 cm 1 foot = 12 in. 1 yard = 3 ft. 1 rod = 5(1/2) yd. 1 furlong = 40 rd. 1 mile = 8 fl.

Develop the functions 'inches_to_cm', 'feet_to_inches', 'yards_to_feet', 'rods_to_yards', 'furlongs_to_rods', and 'miles_to_furlongs'.

Then develop the functions 'feet_to_cm', 'yards_to_cm', 'rods_to_inches', and 'miles_to_feet'.

Your function should have the similar format like this:

def inches_to_cm(x)

    return inches*2.54

Call your function to test your results.

Explanation / Answer

Python program to convert English measurements to metric ones and vice versa.

Code
# 'inches_to_cm', 'feet_to_inches', 'yards_to_feet', 'rods_to_yards', 'furlongs_to_rods', and 'miles_to_furlongs'.
Cm_Inch = 2.54
Feet_Inch = 12
Yard_Feet = 3
Rod_Yard = 5.5
Furlog_Rod = 40
Mile_Furlog = 8

print('9. Furlongs to Rods.')
print('10. Rods to Furlongs.')
print('11. Miles to Furlongs.')
print('12. Furlongs to Miles.')
print('13. Exit')
